It takes time for the moisture to penetrate into the body. I think the 5 years of ambient would be more the culprit than washing the boards. Especially since you are baking them after wash. Get a few of the ICs and put them loose on a board and put

Has anyone seen or put together a good collection of proper handling procedures for components and PCB's? I realize a lot of it is no-brainer stuff, but I need some depth for a training class we are putting together. This would include ESD, Moisture

Questions are: * Does the component take solder when you dip it in the solder pot to test the solderability of the leads? * Can you get full barrel fill when wave soldering a bare board? * Is your flux reaching the top of the board through the hole b

I expect to find the specification and measurement method for the bow & twist of an assembly to be on the assembly drawing. Comments are: * Expecting that an industry committee to write a bow & twist spec for an assembly they know nothing about is n

I am having a problem with some joints on a 100 pin pqfp and few different soics on one particular board. When viewed a 8x with a "Mantis" inspection scope the joints look as though they wetted to the ic leg but when probed the leg will pop loose.

The use of booties isn't required per se, just considered a standard step necessary to reach the 10,000 target. You also need to vacuum (central vac system, NOT exhausting into the room) daily, mop weekly, have a one piece floor, blah, blah, blah....

Dear Friends, I need your help to understand requirements and measurement methods for bow and twist of assembled PCB (PCBA have and SMT and TH components). I already check all posts on the site but didn't found any related to my question answers.

First, we have never repackage devices, as you propose. Our schedule has us standing at Receiving like panting dogs waiting for the material required to jump the job, much less giving up the time and money to have parts repackaged. Second, fabricat
