5 Steps to Eliminate Bridges: 1. Establish (wave) Parallelism First and foremost, you must establish board-to-wave parallelism. This is the prerequisite to any wave solder process control. For an understanding of the power of this approach go to ht

Excessive bridging on SOICW-20, -16, SOIC-8, -14,-16. I've got a board, 4" x 6" w/ SOICs on bottom-side for wave solder. I've checked topside board temp for flux activation, wave height, wave surface with the glass check-plate going from 1" to 2" spa

We're inclined to buy Russ's stuff about peel from the wave. Look here, but shield your eyes first: [ http://www.thepdfshop.co.uk/ppm/defects/Wave/asp/50.asp ] [A respectful bow to BW for the pix] Could you tell us more about: * Board direction thro

�a va Frank? Well, popularity depends on the beholder. Never heard of your "Specnor" machine. US and Eurolanders take different approaches to conveying boards. * US: Finger conveyors * Eurolanders: Pallet conveyors Suppliers of wave solder machin

Brian, a couple of things really stick out here... 1) You are spraying what is referred to here at the CATT as "PINK DEATH" The 3355-11 is about the most active/aggressive flux you can get your hands on. I am concerned about both the condition

Hello Loz, Blue residues on circuit boards can be caused by copper corrosion, component body deterioration, marking permanently, and adhesive break down. In this case, a more subtle mechanism appears to be possible. This is a no clean application
