Are you still looking for that perfect PCB holder? The hefty yet portable Heavy Stainless Steel PCB Holder will rock out when you rework out. These were initially marketed for people doing cell phone repair and rework and we've found this to be an excellent vise for SMT work in particular (this holder is way nicer for thru-hole since you can flip the PCB around) Can fit PCBs up to about 3.5" x 4" (90mm x 100mm)

This flat and dense vise is great because your hands can rest directly on the work table, allowing you to steady yourself with minimal effort for precise soldering and probing. The thick metal plate weighs 430 grams (almost a pound!) and keeps it from moving around so you don't have to worry about the PCB shifting while you're trying to heat up a stubborn component.

Set the length of the three-piece bayonet slightly smaller than the size of your PCB, compress the spring, slide the work-piece into place, and release the springs. Easy, fast, and repeatable.

Features:

• Hold your PCB flat – give your arms a rest! This vise holds your circuit board flat so you can solder more easily at table/desk level.
• Solid stainless steel body with grippy rubber feet 
• Could be used for self-defense if zombies start attacking you in the lab
