The STDC-105 is a 1.27 x 2.03mm Desolder Cartridge Tip for most standard applications. The STDC tips are highly durable and designed for high heat transfer and making desoldering on multi-layer boards much easier. The 700 series tip for use with the MX series and plated-through-hole component desoldering system with the MX-DS1 desoldering gun handpiece. Fixed temperature cartridges and tips offer users a fully safe and thermally effective solution to their lead free soldering needs as well as complete process control. SmartHeat® Technology is unique in that it senses the specific thermal demand directly at the solder pad and delivers the precise quantity and flow of thermal energy during both flux activation and intermetallic bonding phases without any adjustment and calibration.
