We use both the blue static dissipative and black conductive ESD totes to store/transport our electronic assemblies. Our problem is that they get dusty/dirty and periodically need to be cleaned using ESD cleaner and a paper towel. Being that human na

Yes i am trying to install controls. The MSL classification for a part is defined in JSTD033B which i have. I need to update all 5000 plus parts on my MRP system with the correct MSL level (we will be audited on it by BSI). I know that manufacturers

Thank you both ( Gnus and Phil) for the replies. I will try to answer both with a new post. I like the idea of the stock room splitting the reels but our reels are released to the floor where the Magload ( Kit building) area stores them and builds t

I have had Selective issues such as yours on two very different Selective Solder Machines. I was able to eliminate these issues by using Alpha EF-9301 wave flux with any SAC305 solder. It's a more aggressive flux, but really made the difference. Anot

As soon as the oven temp falls below 40 C and the RH rises above 5% then you need to consider that the floor clock will start. Long term storage of devices in an oven is not good for them as it reduced their solderability and can affect their perform

Ok we have to admit that for some reason you went for the used machine, but the $6000 are worth it, I have 2 of the same machine without the NG marker, and in 4 years (the newest one ) and like 6 o more of the old one, there have not been a mech prob

Well, the error occurs with Mod Code 56 (dispenser enable). Head # 1 has installed this accessory, but we use it very little and it wasn't this time. I probed setting 0,1,2 and 3. I downloaded Mod Codes from controller to assembler, then the error b

I have a 208 pin QFP that due to manufacture obsolescence I have to get them form the broker market. I've had several issues with the parts including; bent leads, leads that don't take solder very well, co-planarity problems, and DOA fallout after a

Hi All, I have been looking in to some failures of PCB's in Assembly. After SMT the boards are stored for different periods of time in high humity environment (72% RH and 21.4 degrees Celsius) before being sent to Assembly to be handsoldered/put thr

Hello, Manufacturing process with high moisture and humidity environments and long term storage will definitely see pop corning effects once high temperature from soldering and/or re-flow process. The moisture that has been adsorbed is likely the ro
