Does the file come off of an ICT. Next question is it an AGinet/HP/Keysight 3070. If so you have a chance at finding out the format. It is probably posted online in the Keysight manual downloads section. I might still have an old paper copy of this

First, I don�t understand why your board fabricator can�t do a good job plugging your vias. Additionally, when you consider that they forgot to plug the first batch of boards, it makes me wonder if they are desirable as a supplier. Generally, we us

Lead manufacturing to lead free transisition

Hmmm.... I had Intel survey my process on a mixed alloy line for 2 days. They periodically removed boards from all stations on the line (including post reflow). Boards were "crushed" and spearated into constituent plastic, ceramic and metals. All

Hi, Bill, Lead-free solder and paste manufacturers will be a great resource for you during the transition; they've tested their products extensively, and their application groups have been able to help me through the biggest changes. There are a fe

ICT is generally a manufacturing verification test. Coverages vary depending on the board. I've run lots with as low as 25% coverage on the board (but produced 98% FPY post board assembly). Functional test is exactly what it sounds like. Checking
