Indium Corporation’s WS-575-C Ball-Attach Flux is halogen-compliant (“no-intentionally-added” halogens) and designed as a true one-step ball-attach process for Cu OSP substrates. WS-575-C eliminates many assembly issues, such as missing ball, weak joints, and voiding.
WS-575-C can be completely cleaned using room temperature deionized (DI) water, significantly reducing the costs of heating water.
