Make sure the paper is advancing correctly on your stencil wiper. I have seen this cause major issues. If the paper hangs up, it will smear paste across the bottom of the stencil every time it wipes.

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

I agree. Poor soldering technique is the most straightward way of creating solder balls during hand soldering operations.

I am having cleaning problems when processing PCB's which have TAIYO solder mask on them. After processing, hand soldering and cleaning, a sticky residue is remains, resulting in a cosmetically poor finish with tide marks etc. Other soldermasks do no

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

Could be. What are your profiles? 2) Au finish fail => Could be, but that the connections can be made with hand soldering makes this a low probability cause, assuming the activity of the flux used in hand soldering is not significantly different fr
