In this report, to confirm the effects of heat stress on PCB through holes, we performed the Temperature Cycle Test (air chamber method) and the Thermal Shock Test (liquid bath method). As a result, we found a strong relationship between solder cracking and the life of the copper-plated through hole. In addition, we shall report on our confirmation of the mechanism leading to that failure life.
In anticipation of the InterSolar show, ESPEC has posted a joint press release announcing the sale of a unique solar simulator chamber to WESTPAK.
ESPEC will be exhibiting at InterSolar North America 2010 in San Francisco! Contact us for your FREE ticket today!
ESPEC will be exhibiting at Intersolar (co-located with Semicon West) this coming July in San Francisco.
