While there may not be any specific requirement to cleaning prior to coating, cleaning an assembly prior to coating will only serve to increase the reliability and integrity of the coating. Some residues from low-solids fluxes can interact with conf

Cory, I've got a lot of experience of testing of this type. The physical (not chemical) nature of the flux residues is the crucial issue in compatibility. If you have a softer residue (either caused by a thick initial solder paste deposit, or a low p

Hi Dave, Water soluble flux has two opposite attributes. #1: It is the easiest flux to remove. #2: It is the worst flux to leave behind on a board. As for # 1, there are many de-fluxing systems out there that are very capable of removing water

John, I'm no helicopter guru but maybe someone in these links can help. Good luck-Stevo Mario of MIA Micro-Flight fame has put a very nice diagram of how to hook-up seperate components in a Piccolo board fashion on his website. If you are thinking o

I don't know how I ended-up reading a current trade journal, when I have a stack of intentions behind my desk a foot and a half tall, leaning like a paper Tower of Pisa threatening to avalanche itself onto the underfill materials study, a meager one

This is not a real demanding job. We've talked about materials sources before, check the fine SMTnet Archives. Responding to your question, try: Circuit Repair Rowley,MA 508-948-7973 [Jeff Ferry is a contributor to SMTnet, so ya gotta go there fir

Dear Vicki, If you decide to use high temp paste, I suggest that you verify the rating of the components, especially for moisture-sensitive devices which are normally qualified at peak reflow temperatures of 220-235C. The specified floor life will

I searched the internet to find out more on your plastic fingers and came up with a little info. http://thinkingproductivity.com is the only link I could find for "plastic Fingers" Here is the clip from there site:"We represent Jafco's full line of

Lee, Cal is correct in that Jafco makes the fingers you described. If i remember correctly, they were located in Texas. I had them on an Electrovert in my previous employer. They were about 50% of the cost of the Titaniums. They had their good and ba

Some random Ideas when I read you post...... 1) If it works don't fix it. 2) Be aware of the temp threshold of your components....Over heating components is not good. Over heating is not good period. 3) The Solder paste Chemistry you are using maybe
