LOS ALTOS, CA – Chinese vehicle production is estimated to have risen 12.1% during 2006, according to analyst Henderson Ventures' latest forecast summary.
The research group says world unit vehicle sales rose 4.4% last year, after a 5.2% gain in 2005. Unit production of cars and light trucks is expected to be up 2.9% in 2007, in part as a result of higher-end vehicles with electronic modules.
ATLANTA -- The first revision of IPC-7525, “Stencil Design Guidelines” was circulated for vote in February, and could be published shortly. Among the proposed changes: Refined aperture configurations and area ratios, and new guidelines for printing adhesives.
For its latest revision, the task group behind IPC-SM-840D, “Qualification and Performance of Permanent Solder Mask,” focused on terminology, consolidation, the Pb-free dilemma and test methods.
In a recent interview with Circuits Assembly, longtime task group chair Dave Vaughan, marketing manager, Taiyo America, noted that revision D began simultaneously with the Solder Mask Handbook. In fact, it began with the term “solder mask” itself.
