Indium Corporation releases pink-colored flux for improved visual inspection during production

Indium_PoP Flux 89LV-PIndium Corporation announces the release of PoP Flux 89LV-P, a bright pink-colored, no-clean, thixotropic flux that helps engineers to Avoid the Void™ by greatly improving visual inspection to minimize voiding and other defects in package-on-package applications.

Designed for package-on-package assembly applications, PoP Flux 89LV-P contains a pink dye that is highly visible to the naked eye but is not picked up by automated vision systems. Therefore, PoP Flux 89LV-P does not cause false rejects on equipment that cannot decipher grayscale differences.

“You can practically see our new pink flux from outer space,” said Christopher Nash, PCBA New Product Development Manager. “Of course, that is an exaggeration, but it is very easy to visually inspect. This allows quick confirmation that the flux is present while setting up the process or performing visual process verification.”

In addition to its visual properties, PoP Flux 89LV-P has a unique activator system that provides enhanced solderability onto all common metallizations.
