Cleaning Wave solder fingers and chain

Electronics Forum | Tue Aug 26 13:44:14 EDT 2008 | cgray

The chain and fingers for our Wave solder is getting a large amount of residue from the flux (high dissolved solids) we are using. Any recommendations for products that can clean polymerized flux.

kapton dots and liquid solder mask

Electronics Forum | Tue Aug 09 10:01:26 EDT 2005 | pr

We have some large plated through holes, that we protect with hand placed Kapton dots before they go into the wave. Is there a better option? We are going to see if the boardhouse can put them on for us but I was curious how others are/would do this.

Can anyone help me with the pros and cons of trying to wave solder tantalum and large (1812) ceramic capacitors. I do know that one may see fractures on larger cermaic caps, but have not seen much on the tantalums. Any insight as to what problems I c

Has anyone had experience with placing BGA on gold plated boards. I thought I read a while ago there was a problem with embrittlment causing cracked joints. If anyone has experience with this your feedback would be great. Mike Mike, We and ind

Micro Solder Balls and Vias bridging Issue

Electronics Forum | Tue Mar 03 09:29:48 EST 2015 | rgduval

A couple of things that have helped me with solder ball issues at wave in the past: 1. Flux. Insure good flux coverage on the bottom of the board. 2. Preheat. Insure that the board is sufficiently preheated for the wave operation. Since you're

Has anyone had trouble waving and gluing 0603 R's and C's? At my company, our designers have "opened the floodgates" on bottom-side 0603's. We've got an EPK+ with rotary chip and omega wave but can't seem to get skip-free soldering on these g
