When doing business in China, unlike in the U.S., you may never know what you are getting. This statement comes from over 10 years of experience dealing with the Asian suppliers. The key to dealing with Asian suppliers is to have complete control over your supply chain;  if you don’t, you have now idea what you are getting.

Understanding this principle stems from the knowledge that the Asian businessmen will say YES to almost every request.  It is not in their gene pool to say no. “Yes- we can do it” is said more in the Asian culture than “what’s on TV” in American.  The challenge for American Printed Circuit Board buyers is where and from who is your product coming from. The Asians are excellent logistics and networking specialists. They either have a family member or a friend in the business of something and YOUR product may go to anyone of them.

Case In Point: Years ago, when entering the Chinese manufacturing market, we had a trusted relationship (or what we thought was a trusted relationship) who was a PCB supplier actually give us documentation for supplier A.  They stated they were the factory and were owners and part of the relationship. It soon came to our knowledge they had fudged the UL logo from another factory along with all the paperwork. It turned out that they claimed the PCBs were built in one factory but in fact were built in another factory with the original factory’s UL logo on the PCB and paperwork were doctored. Needless to say we terminated that relationship. It was a brutal awakening to the methodology of how the Chinese go business. There are thousands of middlemen in China shipping out your product to any type of supplier that can meet the price and delivery. You will not know until it is too late if you are really dealing direct!

It is key that if you are sourcing anything from Asia that you have control over you supply chain. PCB Solutions visits China up to, and sometimes more than 4 times per year. We review IPC1710 documents. We conduct quality audits on the factories. We meet the president of the suppliers and insist on following our product through the process flow- forced Honesty and Integrity if you will. We negotiate payment terms (typically unheard of in working with Asian suppliers).  We meet the staff and set our expectations…

So the next time you get the itch to get rid of that U.S. based middle man and play roulette with suppliers emailing you daily, think about what happens when a significant quality issue arises or if you have paid 50-100% of the cost of the product upfront and you have no leverage for a return. Did you consider the cost of wire transfer fees into your costs? How about exchange rates, shipping costs, supply chain control, customs, duties, communication, English skills of the supplier, engineering support, quality of the factory, etc…on and on.

Let our 9 + years of experience work for you. We can, source, stock, label, inventory and even provide secondary inspection on your product if necessary. We lend ourselves to being experts in sourcing Asian based products…don’t get caught trying to learn to be one and spending your quality time fixing problems. Trust the middleman!

As the global economy recovers, the international financial market goes stable, Orders shift crisis also comes to PCB industry for many PCB makers in China. On one hand, the middle-small PCB makers rely on OEM are unable to afford the pressure of cost rise by financial crisis.; on the other hand, serious shortage of workers bring many enterprise embarrassment of shut down. At the same time, with growth of workers wage cost, increase the pressure of the enterprise’s operation. It becomes the question for PCB manufacturers to think how to solve the new crisis.

Besides shortage of workers, PCB makers developed rely on OEM need to afford the affect of financial crisis and the price rise of material, source, energy shortage and high consumption. All this make the process cost rise in China, the price advantage is being eroded. Some international companies already shift the order to the low-cost Southeast Asian, South Asian countries like Vietnam, Cambodia, Bangladesh and Thailand. Under the situation of no significant decline in market demand, cancellation of orders in China, will inevitably be supplemented in other places.

The survey show, Japan IT enterprises have shift their PCB order to Thailand, PCB manufacturing companies in Thailand are also increasingly competitive Data shows PCB industrial value in southeast has already been 3-3.3 billion dollars, Thailand accounts 30-40% of the total. While the famous company like Gree, Supor,  Media, Glanz , Canon and so on have already built their own production plant in Vietnam.

CCL makers posted mixed results for July 2010, with Elite Material (EMC) and Taiwan Union Technology (TUC) seeing revenues continue to move upward, while Iteq suffered a decline in revenues.

TUC saw its consolidated revenues grow 7.5% sequentially to NT$970 million (US$30.41 million) in July, while peer company EMC saw revenues edge up 2.5% sequentially to NT$1.18 billion during the same month. Iteq’s revenues were down 6% to NT$1.77 billion.

However, TUC expects its revenues to continue to grow in August due to new capacity contributed by its new plant in Zhungshan, China. TUC will have total capacity of 1.5 million CCLs by the end of 2010.

For rigid PCBs and flexible circuits combined, industry shipments in July 2010 increased 25.2 percent from July 2009, as orders booked increased 33.9 percent from July 2009. Year to date, combined industry shipments were up 18.7 percent and bookings were up 33.4 percent. Compared to the previous month, combined industry shipments for July 2010 decreased 13.1 percent and bookings went down 16.0 percent. The combined (rigid and flex) industry book-to-bill ratio in July 2010 was 1.11.

“We are still seeing double-digit year-on-year growth rates for both rigid PCBs and flexible circuits as of July,” said IPC President & CEO Denny McGuirk. “July is typically a slower sales month than June, but sales are strong. The most encouraging indicator is the book-to-bill ratio, which continues solidly positive for the 15th consecutive month,” he added. “That is a sign of continuing strength in sales for the remainder of the year.”

The book-to-bill ratios are calculated by dividing the value of orders booked over the past three months by the value of sales billed during the same period from companies in IPC’s survey sample.  A ratio of more than 1.00 suggests that current demand is ahead of supply, which is a positive indicator for sales growth over the next two to three months.

Book-to-bill ratios and growth rates for rigid PCBs and flexible circuits combined are heavily affected by the rigid PCB segment. Rigid PCBs represent an estimated 89 percent of the current PCB industry in North America, according to IPC’s World PCB Production and Laminate Market Report.

The Role of Domestic Production
IPC’s monthly survey of the North American PCB industry tracks bookings and shipments from U.S. and Canadian facilities, which provide indicators of regional demand. These numbers do not measure U.S. and Canadian PCB production. To track regional production trends, IPC asks survey participants for the percent of their reported shipments that were produced domestically (i.e., in the USA or Canada). In July 2010, 83 percent of total PCB shipments reported were domestically produced. Domestic production accounted for 83 percent of rigid PCB and 81 percent of flexible circuit shipments in July by IPC’s survey participants. These numbers are significantly affected by the mix of companies in IPC’s survey sample, which changed slightly in January, but are kept constant through the remainder of the year.

Bare Circuits Versus Assembly
Flexible circuit sales typically include value-added services such as assembly, in addition to the bare flex circuits. In July, the flexible circuit manufacturers in IPC’s survey sample indicated that bare circuits accounted for about 77 percent of their shipment value reported for the month. Assembly and other services make up a large and growing segment of flexible circuit producers’ businesses. This figure is also sensitive to changes in the survey sample, which may occur at the beginning of each calendar year.

Interpreting the Data
Year-on-year and year-to-date growth rates provide the most meaningful view of industry growth. Month-to-month comparisons should be made with caution as they may reflect cyclical effects. Because bookings tend to be more volatile than shipments, changes in the book-to-bill ratios from month to month may not be significant unless a trend of more than three consecutive months is apparent. It is also important to consider changes in bookings and shipments to understand what is driving changes in the book-to-bill ratio.

The information in IPC’s monthly PCB industry statistics is based on data provided by a representative sample of both rigid and flexible PCB manufacturers in the USA and Canada. IPC publishes the PCB Book-to-Bill Ratio and the PCB Statistical Program Report each month. Statistics for the previous month are not available until the last week of the following month.

IPC announced strong book to bill ratios for June 2010 and PCB Solutions saw equally good ratios. We are curious to see how the industry fared in July as we saw a dramatic slow down symbolic of the quietness of 2009. We at PCB Solutions are confident we never pulled out of the recession but just seem to be maintaining aggressive web marketing and sales approaches for organic growth and profitability.

As we hold our strategy at PCB Solutions, we will ride out this market in a very strong, competitive position.

In 2009, the output value of the global PCB industry reached about US$40.6 billion, down 15.83% over 2008. This was mainly caused by continuously decreasing PCB shipment and average prices. As for main sub-sectors, the output value of the global substrate, rigid PCB and flexible printed circuit (FPC) board sectors descended by 50%, 20% and 3.8% respectively compared with 2008. The decline of the global substrate and rigid PCB sectors is mainly due to the sharp drop of sales volume of desktops and medium to high-end notebooks. In comparison, the global FPC board sector declined more slightly in 2009, thanks to the growing number of LED backlight modules and Smart Phone FPC boards as well as the touch panel boom.

From 2000 to 2009, in terms of output value, computer, communications, industrial/medical, military and automotive PCBs decreased by 3%, 13.5%, 20.5%, 20.1% and 26.8% respectively, while consumer electronics PCB and package substrate increased by 15.8% and 68% respectively. Single-sided/double-sided PCB and multilayer PCB decreased by 37.3% and 25.2% respectively, while high-density interconnect (HDI) board, package substrate and FPC increased by 163.1%, 68.1% and 90.0% respectively.

In 2009, from the perspective of the global PCB distribution pattern, Mainland China, Japan and Taiwan were still the main production areas, South Korea continued to expand its PCB industry, while Europe and the United States were in recession. Compared with Japan and South Korea with advantages in high-end products such as IC substrate and FPC board, and Taiwan with advantages in mobile phone PCB, China, mainly engaged in single-sided PCB and multilayer PCB, is inferior in terms of the technical content of the PCB industry.

In 2009, China’s PCB industry for the first time saw its output value decline slightly by 3.6% to US$16.35 billion. Nevertheless, its share in the global PCB output value continued to rise. Among China’s top 100 PCB enterprises in terms of sales revenue, local ones performed well, for example, the sales revenue of Bomin Electronic rose by 150.7% over 2008.

Here is to a better 2010…

Conductive (Silver Filled) Epoxy:

Conductive silver filled epoxy contains organic solvents which require storage at a temperature of less then 5 degrees C, and limit the shelf life of the material.  Because of this, many PCB factories do not stock this epoxy and purchase it in quantities needed for the order, which may cause delays in production.  The size of the silver balls in the epoxy can make filling smaller holes difficult and often lead to air pockets inside the hole, which will actually decrease the thermal conductivity of the hole.  If the air pockets are close to the surface, this can cause voids at the pad surface, leading to assembly issues.  As the CTE (Coefficient of Thermal Expansion) of Silver Filled epoxy can be very different from the CTE of high TG material used in lead free or ROHS assemblies, blistering of surface pads can be common, as well as lifted pads during high temperature soldering operations.

Silver filled epoxy reacts to process chemistry during metallization by expanding which will cause an uneven or swelled pad surface.  This creates the need to add an additional process of “planarization” of the pad surface which can be costly, time consuming and add to pad surface imperfections including dimples in the land pattern and voids that can outgas during assembly.

Non-Conductive Epoxy:

Non-Conductive epoxy is 100% solid epoxy material which usually yields good pad planarity for via-in-pad designs.  The lack of silver in the epoxy resin allows the process to be used on smaller holes, including micro-vias often down to as small as .004 inch.  The CTE (Coefficient of Thermal Expansion) of non-conductive epoxy is often very close to that of high TG material, meaning less issues with hole expansion during the assembly process.  This also allows Non-Conductive Epoxy to be used in sequential lamination processes to fill blind and buried vias.

Non-Conductive Epoxy usually exhibits very little shrinkage during the thermal curing process, which will yield good pad planarity and will not require a separate planarization process.   The flat surface of the pad after plating over the Non-Conductive Epoxy means less chance of lifting pads during the assembly process and greater rework ability.

As there are no temperature or shelf-life restrictions to Non-Conductive Epoxy fill, most PCB factories have a ready supply of the material in stack, thus eliminating production delays caused by material procurement.

Effects on Thermal Conductivity:

Improved thermal conductivity is often cites as the reason for choosing Conductive Epoxy Fill over Non-Conductive Epoxy fill.  It is true that pure silver has the highest thermal conductivity; however, when surrounded by epoxy the silver surfaces are insulated and there is no direct contact of the silver to effectively increase the thermal conductivity.  Additionally, the air pockets present when using Silver Filled Epoxy may also reduce the thermal conductivity.  A properly filled and capped plated through hole will have better thermal conductivity using Non-Conductive Epoxy fill in place of Conductive Silver fill.

Conclusion:

The development of improved formulations of Non-Conductive Epoxy fill have created an equal or superior bond to electroless copper and increased the Thermal Conduction of filled holes, while eliminating many of the manufacturing and assembly concerns with Conductive (Siler Filled) epoxy.  Due to the points raised above, PCB Solutions strongly recommends Non-Conductive Epoxy
