S-T9000X Solder - Kester, 60 / 40, 44 Flux, 1 lb spool
60/40 Rosin Core, 1 lb Spool, contains lead alloy. Kester 44 Rosin Flux is an activated rosin formula for use in flux-cored solder wire. Kester 44 Rosin Flux has virtually dominated the field of activated rosin core solders for well over four decades. An outstanding performance feature of this flux is the “instant-action” wetting behavior.

S-H190 Standoffs - 0.18", plastic with adhesive backing
Package of 8
Low-profile adhesive standoffs with a 0.180" standoff height that securely attaches your PCB to a flat surface. The post inserts into a 0.125” mounting hole and includes a locking tab that secures the PCB when inserted. It can be used with 1/16” or 1/32” thick PCBs. The 0.6 x 0.6” square base is offset to allow the base to be underneath the board when the mounting hole is close to the PCB edge and the offset base provides a large sticking surface while permitting the PCB to be mounted in tight spaces or close to walls. This can be useful when working with small enclosures. High-quality 3M™ brand double-sided tape secures the standoff to a flat surface. These standoffs are available in packs of 8, 24, or 100 pieces Features:
  • Low profile 0.180" standoff height.
  • Offset base allows use when holes are close to the PCB edge.
