Solder Paste

Offering an array of solder pastes for stencil printing processes, meeting IPC standard J-STD-004 for size (Particle Types 1 – 8) and for Flux, including Rosin based, Water Soluble, and No Clean.

Solder paste is offered with optimums for viscosity, slump and working life in mind.  And due to recent developments in the market, the first-ever temperature stable solder paste is offered (stable at 26.5 degrees C for one year and at temperatures of up to 40 degrees C for one month), providing benefits in logistics and the operation chain.
