Q: How to protect connectors of SMT placement equipment from solder smoke corrosion?

A: Choose connectors with PBT shell material (high-temperature resistant engineering plastic, heat resistance up to 150℃), such as the XS series. The gold-plated contacts (thickness ≥3μm) can resist corrosion from sulfides and chlorides in solder smoke, extending the service life to over 3 years (ordinary nickel-plated connectors only last 1~2 years). If the smoke concentration is high, an additional dust cover can be installed to reduce the entry of pollutants.
