As the August books come to a close, PCB Solutions is happy to report steady and strong Printed Circuit Board Sales. While 2009 was tough year for manufacturing and distribution in the electronics industries, 2010 has proved to be a decent rebounding year.  At the end of August, PCB Solutions stands at a 69% increase over ytd sales in 2009.

PCB Solutions continues to see solid sales from internal house accounts and modest growth from Reps and Web leads.  PCB Solutions remains very optimistic about its growth on the web as it has rise to  the 20th position for the key search term “printed circuit board;” which is one of the most competitive key search words in the industry. Web marketing efforts by www.infogenix.com are proving great results by branding the www.pcb-solutions.com domain on line.

As PCB designers face greater challenges with fine-pitch components, less real estate and greater need for thermal conductivity, the use of epoxy filled vias has become common.  With two very different options of non-conductive and conductive (silver filled) epoxy available, the question if which is best often leaves designers and engineers with a difficult decision to make.

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

Something that electronics purchasers are suffering from at the moment is long delivery times on printed circuit boards. Something that often occurs during economical upturns.

The PCB delivery shortage is partly due to the limited availability of PCB laminates. In turn this is due to increased copper deficiency, something that happens in most economic upturns. This has resulted in a sudden price increase for the laminate. The price increase in China is around 20% and in extreme cases 25%. This price increase is not reflected fully in the total PCB price. If the laminate price in China increases by 20% the PCB price tends to increase approximately 15%, a source told Evertiq. It is also more likely that price increases are higher from Chinese manufacturers than from European manufacturers, the source noted.

PCB delivery shortage is not the biggest problem that electronics buyers today are suffering from. The lack of components allow buyers to wait even longer after the PCBs have been delivered. Several semiconductor giants have delivery times around 20 weeks at present and 3 days just to get the components out from the warehouses, according to an electronics purchaser. It has happened several times that many component manufacturers have not prioritized to recognize purchasing orders.

Several European PCB manufacturers told Evertiq that they are running on full production at the moment. On the PCB-trading side, the average delivery time on trading volumes from PCB distributors is 5-6 weeks. Just a few months ago, the delivery time was 3-4 weeks.

BANNOCKBURN, Ill., USA, March 25, 2010 — IPC — IPC — Association Connecting Electronics Industries® announced today the February findings from its monthly North American Printed Circuit Board (PCB) Statistical Program.

PCB Industry Growth Rates and Book-to-Bill Ratios Announced
Rigid PCB shipments were up 9.4 percent while bookings increased 36.4 percent in February 2010 from February 2009. Year to date, rigid PCB shipments were up 3.6 percent and bookings have grown 27.9 percent. Compared to the previous month, rigid PCB shipments increased 4.7 percent and rigid bookings increased 8.1 percent. The book-to-bill ratio for the North American rigid PCB industry in February 2010 grew to 1.09.

Flexible circuit shipments in February 2010 were down 2.1 percent, but bookings were down 37.4 percent compared to February 2009. Year to date, flexible circuit shipments were down 3.1 percent and bookings were down 0.4 percent. Compared to the previous month, flexible circuit shipments went up 4.9 percent and flex bookings fell by 36.4 percent. The North American flexible circuit book-to-bill ratio fell below parity to 0.92.

For rigid PCBs and flexible circuits combined, industry shipments in February 2010 increased 8.5 percent from February 2009, as orders booked increased 29.1 percent from February 2009. Year to date, combined industry shipments were up 3.0 percent and bookings were up 25.6 percent. Compared to the previous month, combined industry shipments for February 2010 increased 4.8 percent and bookings went up 4.5 percent. The combined (rigid and flex) industry book-to-bill ratio in February 2010 increased to 1.07.

“Rigid PCB bookings have outpaced shipments for the past 11 months. That’s reflected in the high rigid PCB book-to-bill ratio and it’s an encouraging indicator of future growth,” said IPC President & CEO Denny McGuirk. “We saw a big drop in flexible circuit orders in February, but no sign of a trend yet, due to the volatility of flex orders and sales.”

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 90 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 February 2010, 83 percent of total PCB shipments reported were domestically produced. Domestic production accounted for 85 percent of rigid PCB and 68 percent of flexible circuit shipments in February 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 will remain 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 February, the flexible circuit manufacturers in IPC’s survey sample indicated that bare circuits accounted for about 56 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 three consecutive months or more 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.

U.S. Tech Market Shows Signs of Life
A Refresh Cycle At Last

April 10, 2010
By Larry Barrett

Thanks to a boost from a substantial corporate upgrade cycle and the improved demand for strategic software investments in Software-as-a-Service (SaaS) and service-oriented architecture (SOA) projects, the U.S. technology market is poised for robust rebound in 2010, according to Forrester Research’s latest report.

After years of delaying or truncating investment in new equipment and software, enterprise customers are finally opening up their wallets for IT purchases that improve overall organizational efficiency and help companies differentiate themselves from their competitors, researchers said.

“The tech downturn of 2008 to 2009 is unofficially over,” Andrew Bartels, a Forrester vice president and principal analyst, said in the report. “With growing evidence that an economic recovery started in the US and other countries in Q3 2009, the pieces are in place for a 2010 tech spending rebound.”

In 2010, Forrester is predicting the total U.S. IT market will grow 8.4 percent, up from the 8.1 percent improvement it previously forecast. It now expects global IT spending will improve about 7.7 percent this year, a little slower than it previously forecast mainly due to international currency fluctuations.

Computer equipment, particularly the replacement of older PCs, servers and storage equipment, is now expected to surge 11.1 percent from 2009 while software sales will improve 10.5 percent.

“For software, growth will result from a mixture of the revival of deferred licensed software purchases following the 2009 capital freeze, ongoing growth in SaaS software, and continued strong growth in smart computing platform technologies like service-oriented architecture (SOA) infrastructure, virtualization software, and analytics,” the report said.

Computer equipment sales are now projected to rise to around $83 billion with PCs accounting for roughly $39 billion of that. Communications equipment will top out at $108 billion, while telecom services and IT services and outsourcing spending will check in at $191 billion and $165 billion, respectively.

Total U.S. business and government IT spending will total more than $741 billion this year, of which about $194 billion will be spent on software — the single largest category. New applications will represent $88 billion in investment, followed by custom applications at $43 billion and middleware and operating systems software coming it at $52 billion and $11 billion apiece.

Forrester’s findings dovetail with early projections from major manufacturers, software developers and independent research firms.

Gartner earlier this year predicted total PC unit shipments would improve more than 20 percent this year to a total of more than 366 million units shipped, up from 305.8 million units in 2009.

By industry, Forrester expects U.S. financial services and insurance companies to increase their total IT spend by 11.4 percent this year while manufacturers and telecom companies will ramp up their IT spending by 9.8 percent and 9 percent, respectively.
