Hi Leadthree, We have a combination of methods depending on volume, value, size, level of build, and what the customer does with them. So on high volume low value we have rigid plastic ESD boxes with lids, foam lined, that layers of custom vac form

My company is a small to mid size contract manufacturer, and relatively new to the business. I was wondering if anyone could tell me what a typical warranty policy is for PCB assemblies. In an effort to get needed sales, I am afraid our sales departm

The problem expressed by you need not necessarily be caused by the Reflow process even though it's effect cannot be ruled out. I suggest to validate periodically the Reflow Oven performance as also optimise Reflow parameters through a documented vali

Smartasp, Seems this issue is certainly making a long thread ! As far as our Experience is concerned on Reflow Soldering, particular parts must have failed in LSLs [Lower Specification Limit] and have not withstand well under USLs [Upper Specificat
