For rigid PCBs and flexible circuits combined, industry shipments in June 2010 increased 24.4 percent from June 2009, as orders booked increased 27.8 percent from June 2009. Year to date, combined industry shipments were up 17.6 percent and bookings were up 33.4 percent. Compared to the previous month, combined industry shipments for June 2010 increased 14.8 percent and bookings went up 8.6 percent. The combined (rigid and flex) industry book-to-bill ratio in June 2010 was 1.12.

“The book-to-bill ratios for both rigid PCBs and flexible circuits remain well above parity, which suggests a positive outlook for the remainder of the year,” said IPC President & CEO Denny McGuirk. “Sales growth is stabilizing, but year-on-year growth in both segments is continuing in double digits,” he added.

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 June 2010, 83 percent of total PCB shipments reported were domestically produced. Domestic production also accounted for 83 percent of rigid PCB and 81 percent of flexible circuit shipments in June 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 June, 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.

PCB buyers struggles with long delivery times

James Brown — Wed, 14 Apr 2010 16:39:29 +0000

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.

RoHS – Do I need a High Tg Laminate?

James Brown — Mon, 15 Feb 2010 23:51:29 +0000

Through the years, the printed wiring board industry has had to evolve in both materials and processes to meet the needs of the world’s electronic challenges. At first the laminate resin systems were inadequate to survive thru multiple thermal excursions of double-sided assembly and rework processes, then the need to meet the high speed signal integrity requirements were needed and now because of the environmentally friendly initiatives of RoHS have again asked the industry to step it up.

Currently most printed wiring boards can meet RoHS (Restriction of Hazardous Materials) directive requirements as long as the boards’ surface finish does not contain lead. Most if not all laminate manufacturers have already removed or reduced mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ether levels to meet the directive. The challenge has been how to reliably attach components to the PWB without the use of lead, which have higher temperature and longer oven dwell times due to lead free metals being used. For this you need to look at the laminate materials Td rating (Time to Decomposition).

That’s right, even though material Tg has been the main focus of a laminates ability to survive temperature for years, it is not as important as the material’s Td.

Td is the measure of how long a material can handle the higher temperatures of the assembly process. Materials are more thermally resistant as evidenced by their higher Td rating and their ability to achieve a T260 or T288. A T260/288 (Time to Delamination) is the amount of time the material can withstand exposure to 260 / 288°C.

However, if you have a low cost double sided board that requires the use of lead free solder, it may not necessarily mean that you need the higher Tg/Td laminate. Talk to your assembler; you may be spending more than you need to on raw material costs, and being that laminate costs are the single highest material cost of the printed wiring board, it may be worth running some tests by subjecting boards to multiple Pb free reflow cycles to verify it’s resistance to delamination and blistering.

It is true that lead free solder does require higher reflow temperatures and longer dwell times but if the overall density of board is low, it will reflow faster because the entire structure heats up faster and does not require as long of a time in the assembly ovens to get up to the necessary reflow temperature to make a good solder joint, the lower Tg/Td material can reliably withstand the assembly process. Keep in mind that even standard 130dC Tg laminates made today are superior materials that meet RoHS requirements and work well for many different applications and in many cases can take a the thermal excursion of lead free assembly.

On the other hand if you have an expensive multilayer board that has a lot of copper planes, high density, it takes the structure much longer to heat up in order to reflow all the solder joints, in this case you need the extra assurance of high Td rated laminate systems.
