Circuit Board Heat Gun

You can salvage most any surfacemount bga or even through hole parts using this method.

Circuit board heat gun.

I m curious how well a hot air gun would work for reflowing an entire board. Here s what i was thinking might work. While a regular hot air solder rework station could cost more than 100 a common heat gun available from most home improvement stores should cost no more than 50. I using a old harddrive as a example.

The heat gun was under 10 and it is really usefull to have around. Hot air soldering is customarily used with surface mount devices being attached to printed circuit boards.

The goal of this instructable is to demonstrate how to make a circuit board pre heat workstation for around 50 00 with no special tools and the majority of materials from.

A common heat gun is an inexpensive way to reflow or reattach electronic components that have been soldered together. Apply leaded solder paste via a stencil onto the pcb.

Because hot air guns heat up a large portion of any pcb you re working on they can also cause significant damage to other components as well as the board s laminate. And because hot air guns aren t as accurate as rework stations your resulting work area can wind up being pretty messy.

My circuit board has about 250 components including 0402 passives and a couple of 0 5mm pitch tqfps and it s a bit of a pain to assemble it using a soldering iron.
