Overview
A small repair bench with a lead-free requirement is the place for this Chip Quik low temperature paste. The syringe holds a bismuth-bearing tin alloy in a synthetic no-clean flux vehicle.
The reason to buy it is a very small lead-free syringe for occasional low temperature joints, with a no-clean flux. The limitation is the cold storage and warm-up routine, which is a lot of handling for a small quantity.
Who it's for
Repair benches and hobbyists with an occasional lead-free joint to make will find the small syringe a manageable quantity. Production lines, and anyone needing a leaded or high melting alloy, should choose a larger or different product.
Pros and cons
- Small syringe quantity
- Low melting temperature
- No-clean synthetic flux
- RoHS and REACH compliant
- Needs refrigeration and warm-up
- Limited quantity for repeat work
Performance notes
The paste liquefies at a low temperature, so the board and parts take less heat during the joint. It must warm to operating temperature after refrigeration, and stencil life is longer at lower humidity. Stencils can be cleaned automatically or by hand with isopropyl alcohol.
