I am seeing a problem of flux droping on the PCBA during reflow. This is a pb free process and I am using KOKI pb free paste with 8 zone (and some 9 zone) reflow ovens. Line throughput is about 10,000 boards/24 hours. I suspect that the exhaust is no

J-STD-001C just requires that the area not be so dirty as to contaminate your product, tools, workspace, etc. If you start counting particles, you're into cleanroom territory. Do a search on ISO 14644-1 for specifics. Actually Wikipedia does a ni

Hey Guys, We are looking to set up a line to manufacture low volume high mix PCBs. We have work in the display technology and military sectors. Part tracking, lot tracking are critical. The machine may also end up in a class 10,000 or 1000 clean room

Now I need to select a AOI machine. There is a problem. My company have a non-stop production process of different PCB. One manufacturing process can be 24 - 48 hours long ( about 2000 to 10000 PCB from different costumers) and so I need to find AOI

Never use a water softener for defluxing. They add sodium to the water which is bad for boards. The white residue may be flux. If that's the case, either the dishwasher is not powerful enough or the wash water is not hot enough. Another possibili

Kic Thermal used Pyropel. Cut with a razor blade and glue together with a good Dow Corning high temperature silicone. You can buy Pyropel in various thicknesses. It is not cheap. $100.00 for a 24" X 24" X 3/16" sheet. You can buy at McMaster Car

Hello, colleagues! Please help make a choice! (MY500 + MYDATA MY100 + Heller Mk1707) or (Dec Horizon03 + Samsung 421 + Essemtec RO400FC-C) or very cheap Korean equipment (Sj InnoTech; HP-520 + Mirrae Mx350P + TSM; A70-i71). The volume of required c

Let's put it this way - if you run 10000boards every month, you could probably go this route and have a 100% inspection on everything. I work for a high mix low volume company and we will never do this excessive work. I would always focus my attentio

That is very dependent on what components are needed for your boards. In general if you are running high volumes you talk directly to the manufacturers. If they think your 10,000 boards ain't worth getting out of bed for, they will refer you to thei
