I had problems with white residues on both WS609 and WS 3060.The WS 3060 turned out to be a carbonized material.The composition after analysis (Energy Dispersive X-ray spectrum) turned out to be tin,tin,phosphore and cloline and tin. Alpha also have

Hi mates, need your advise here. we have solderballs on a model due to neglect by stubborn folks to follow issued process control instructions. the post-reflow PCBA has solderballs stuck in the NC flux residue and is not in compliance to IPC-A-610

Hi mates, just my 2cents worth... some folks (like us) have product runs that have BGA using no-clean, coupled that with Class3 IPC-A-610 specs, topped with aerospace/military customer defined specs. we end up cleaning NC with a degreaser machine w

Hello Mark, I'll assume that you are currently wave soldering and would like to eliminate that operation by using pre-forms or press-fit connectors. Solder preforms or solder flux bearing connector leads usually do not require any hole size changes,

Various solder metal supplies sell pre-forms as loose individual shapes, usually donuts. The loose performs then are placed on the connector leads. If you have any volume at all, you would want to look at a �shake table� that would vibrate a batch of

What you are seeing on your gold fingers is referred to as flux spattering. This is a very commond problem with gold fingers if you have a zero flux spattering criteria for quality control. The key to eliminating this problem is in the reflow profi

Guys, Thanks for the input. Its a Opto-Electronic project I'm working on for a customer with a device on a ceramic substrate. Yes, I did learn from Indium that 007 is no-clean and has a high-solids content. They reccommended using TacFlux 010, which

I can't think of any off hand other than the Ersa which is massive and from when I used it a pain in the A*SE to program and keep programmed, you always seem to have to baby sit it. I bet if you asked you could get one, the problem is that forced con

We don�t use this glue. What does Heraeus say about your condensate? [I'm With the previous poster. Your condensate sounds like goop from NC flux not glue.] How to clean out a 3 meter length of chimney? Depends on your tolerance for pain * Take

I use Kyzen's Aquanox SSA cleaner in a heated parts cleaning tub to clean anything with flux condensate on it. When heated to 120F, the stuff melts away like ice under hot water. When the cleaning solution is loaded, I send it in an evaporator. The s
