A couple more things to look at. ( DEK) Check you wiper blades. This is the rubber blade that holds the paper in contact with your stencil. When these wear down it will not clean properly. Also make sure when you run this product that you verify that

We have two ZipaTec 460s Selective Solder Machines, one for Lead and one for Lead-Free. This morning we noticed the solder pot was covered in solder balls, and after asking the operator what they had run, the answer was "Nothing." The operator had al

Solder spattering, solder balls, components "popping" off pads........ Not a serious chemical reaction, however, as replied to by KEN on 12/21/04 in a similar article: "Are you adding liquid flux? Or paste "Gel" flux? If liquid flux: This, in my m

Are you adding liquid flux? Or paste "Gel" flux? If liquid flux: This, in my mind, is an unacceptable technique. Why? 1. Can not control metals content. 2. Probably not adding the same chemestry flux...as paste flux has many different addi

Wolfgang: Boy it's tough to convey context in this medium, isn't it? Clipped from our paste storage work instruction, environmental effects on paste are: 1a Avoid excessive heat (over 80� F). It causes flux separation, reducing print quality. 1b

There are several different technologies in the industry today to assist in the out-gassing of flux cores. On automated soldering systems, there are two main types of perforating solder feeders: - Hole Drilling - "V" Scoring By perforating the so

Hi Jacky, It seems you have solder bead problem, beading occurs when the solder paste brick splatter as a component is placed into it, after reflow, the splatter becomes a spherical solder ball. Hope this will help. Steve USA STENCILS

Hi Any, This is from an earlies thread "Solder Ball After Reflow Process". Date: August 16, 2006 01:52 PM Author: Russ Subject: Solder Ball After Reflow Process Oven settings are meaningless here. What does the board see? It is the paste we a

I recently had the same problems, solder bridges on every thing I made, different customers boards, etc. I wave with no-clean flux. As I sorted out problems (pin holes, blow holes, splatter, etc.) I found a lot of variable factors. I changed flux,
