Solderability Testing of Printed Circuit Boards—For Free Circuits Assembly Bob Willis presents an easy method to test solderability of pcb's, using a testpattern on the scrap area of the board and a mini stencil. (added on 13-Jan-2003)
The Wetting Balance Circuits Assembly This is part 1 of a 3-part series. It discusses the use of a wetting balance for quality control and process development, and explains why the wetting balance is superior to traditional methods of solderability testing. (added on 24-Aug-2003)
Solderability Electronic Production Electronics Production Magazine does not exist anymore, but their extremely usefull online-encyclopedia is still available from SMTinfo.net. This part gives an introduction to solderability.
The Wetting Balance—Part 2 of a 3-Part Series Circuits Assembly In this second installment of this series, the use of a wetting balance as a process development tool is detailed. Although traditionally regarded as a quality control (QC)/quality assurance (QA) tool, the wetting balance can be used in all areas that pertain to soldering and solderability. (added on 27-Apr-2004)
The Wetting Balance: Part 3 of a 3-Part Series Circuits Assembly In this final article of this series, we explore the proposed change to lead-free alloys—SnCu for wave soldering and SnAgCu for reflow—and how they will impact solderability testing, assembly issues and the necessity of returning to nitrogen inerting to widen the process window.
