Manual lead tinning station saves time and costs for re-tinning fine-Pitch QFPs
The MLTS is suitable for both smaller assembly houses as well as larger contract houses with dedicated assembly work cells. Engineers no longer need to send their components to a tinning house with the associated delays and expenses. The MLTS employs a unique tinning method using a specially designed “side wave” solder nozzle that is heavily purged with nitrogen. The side wave process uses the natural cascade of the solder to scrub the old plating off while wicking away excess solder during the extraction of the forms leads leaving the leaded array bridge free.
This process is so robust that even tinning FPQFPs by hand holding the components with a vacuum wand works very well. The MLTS is an ergonomically designed work station for one person to easily handle all forms of component lead tinning. It can be configured with one or two solder pots with either the “side wave” or straight “immersion” nozzles, and flowing flux station. The solder pots and fluxers are operated through foot switches minimizing the solder pumping and keeping N2 consumption to a minimum.
