Off the Cuff Answer: Wow, nice big ugly connector! Thought we were the only ones using these things designed during the Korean war. Actually it really depends on the customers print. If they want conformal coating, they should know exactly where

I thought I already DID fall on my head and that's why I'm here..... I think you got something with the ESD coat Rob. You could market it as "The Process Profesional ESD Smock" (Lead Free smocks available soon). It would be like a regular smock or

We use the SC-205 head and we are pretty satified (just keep everything clean and keep a constant viscosity to eliminate nozzle problem). I'm not sure what you mean by keep out area but you can determine with quite precision by software where you wan

Hello, I have recived from customer PCB where he found that big SMD electrolytic capacitor just fell off. I checked this boards (FR4 , Au/Ni coating). I noticed that all solder remained on the termination of capacitors and looks ok but on the boar

I used 1' of McMaster part # 8821K6 (0.110" thick). It is rated to 600F. I believe I put four layers over my profiler but I'd recommend starting with two. If you need more you can add it. Make the sock good and tight because the fabric seems to h

IMHO I would avoid sprayed silicones like the plague. They can travel around your facility and cause solder wetting issues that you will never know the root cause for. Also found this e-drive article on using silicones around motors and relays. Loo

I'm not that concerned about the solderability of the motor. Our customer is concerned about the outgassing of the conformal coat effecting the motor brushes. Silicone will break down into SiO2 and SiC will result from a spark between the brushes a

The short answer is immediately after reflow the problem occurs. To be more exact, what you are describing is not "rust". Rust occurs in iron. The oxidation that occurs in Tin-Lead has been sometimes called "white rust". Either way, oxidation occur

We've been using a series of relatively high durometer rubber molds to protect male headers from conformal coating here in our facility for quite a while now. They are black in color and are sold in strips that can be cut to desired lengths. Unfortun

Another thing I'm curious about. What is the "functional purpose" of soldering stainless? Solder coatings generally prevent oxidation on surfaces, but why would somebody solder STAINLESS? Stainless, by nature, is resistant to rust, and hence, oxid
