Quality is NOT a Saying, Quality is a Mindset at STHL.

Material Control at STHL

STHL offers one-stop electronics contract assembly services both partially turnkey and full turnkey orders. We always carry out strict quality and process control includes material inspection, storage conditions and production process. Due to components and materials of different characteristics, there must be strict control of temperature and moisture conditions. We control the solder paste and all other materials with the first-in-first-out principle.

More Details about STHL Storage

Why must Integrated Circuits and PCB boards be baked before being SMT assembly? Baking integrated circuits and PCBs is to remove the moisture which can cause voiding and de-lamination during cure. From surface mount components, it is also possible to get “popcorning” of components that are attached with surface mount adhesive. Baking boards at temperatures above 100C will guarantee that all the moisture will be eventually removed. At STHL Technology, we have baking and thermostat machines to work this process for necessary materials.
