Ultrasonics, coupled with an aqueous detergent process that cleans at below 43°C, may be best suited for fine-pitch SMT screens and stencils. Aqueous detergents clean more effectively than solvents, with little or no environmental impact. Because of the environmental concerns driving ...
The stencil cleaner can be one of the most versatile tools on the manufacturing floor. It can be used to clean electronic modules in various stages of the manufacturing process. In fact, an automated stencil cleaner can clean just about anything you come up against in your PCB assembly process.
Main Points: * Technologies for the job * More than a flat piece of Stainless * Compatibility * Solubility in stencil cleaning * Influencing factors * Best Practices to reduce misprints and increase yields
Solder paste screen printing is known to be one of the most difficult processes to quality assure in Printed Board Assembly (PBA) manufacturing. An important process step in solder paste screen printing is the under stencil cleaning process and one of the key materials in this process is the cleaning ...

ENIG; Au < 0.5 um to avoid solder joint embrittlement -- We are designing a new PCB that will include a 0.4 mm WLCSP IC package. The OEMs application-note for this package states ENIG; Au < 0.5 um to avoid solder joint embrittlement. Our PCB fabricator specifies the ENIG Au thickness to be 0.04um, with a range of 0.05um to 0.125um typical. If the Au thickness is 0.125um on some PCBs, will this cause any placement/soldering/reliability issues for the 0.4 mm WLCSP? Thanks, Joe
