What are you going to fill the chamber with when it needs to be opened? If you use air, will the evacuated components suck up any available moisture? I've never done anything like this with electronic components, but some of the more porous materi

Jon, The machine keept the positions / offsets ECT. I think just the battery back up went on the CPU brd due to the flood watters and it looks like it just affected the brd data.I will be trying reprogramming a new brd in the morning. I will call yo

Many years ago, we used to double print. The way we did it was with a rubber squeegee set to do a flood stroke, followed by a return cleaning stroke with a metal squeegee. Why?! Well, this was in the days before Laser etch, and because the chem bat

Well if you are getting bridges under, one thing that we used to do was flood the part with flux and then run it back through the reflow. Keep in mind we were not a High reliability manufacturer. This practice didn't hurt OUR boards, and most of the

I have to build test fixtures for RF Power transistors. These components generate alot of heat so the PCB is soldered to a baseplate. The problem I am having is that I am getting too much solder flowing thru the via's and flooding the topside of th

I am going to open the flood gates of comments. The purpose of no clean is so you do not have to clean it. Yes I am aware of no cleans that you can clean. If you need to clean the boards use a water soluble paste. If you do not clean, no clean prop

Read the articles everyone else recommend. I haven't read of them but I will say this. A Solder Mask Defined pad is a copper flood that has much more thermal mass than a Non-Solder Mask Defined pad so it will heat and cool at a slower rate. I suspect

Hi! I have just checked in my same oven after a blower-defect. You need Carlo Gavazzi EC3016PPAPL-1 sensor. You can find a link here about the sensor, use it as reference: https://us.rs-online.com/product/carlo-gavazzi-inc-/ec3016ppapl-1/70014680/ It

Dave, There is not really a �smart� or scientific way to check this but I know of easy ways and very effective ways. Fex. an easy way to check is with a 3� spatula, you hold the spatula at the same angle as the board and drag trough the wave simula

Hello to everyone, Have you ever experienced soldermask bubbles inmediately after printed the soldermask itself? (for screen printing method of LPISM). I am not talking here about blistering or any outgassing defects after exposing to high temperatu
