Introduction: Get Electronic Components Fast!
Have you ever wanted a bunch of components from an old pub, but don't want to waste an eternity with a soldering iron and pump? Look no further! Just follow these simple instructions and you'll have plenty of random components that you can make stuff with!
Although this may not be groundbreaking news, it is a trick i learned from a teacher i had a while back who also does electronics in his spare time (but, the old school stuff).
Step 1: Stuff You'll Need
A heat gun (mine is a wagner model from home depot for 20 bucks)
An old PCB (mine is from a CRT TV)
Probably want a vice, but if you lay the PCB down so that the components fall out on the floor, thats good too.
Some needle nose pliers (they'll work for all but the beefiest of components)
A glove (to protect your hand from heat)
Step 2: WARNING
The heat gun + the PCB = stank @$$ fumes. Be in a well ventilated room, preferably with a fume fan and an open door or window
Also, work over concrete or treated wood so that you don't set things on fire. Heat guns can blast air over to 700 degrees fahrenheit, so if you use carpet, you're gonna have a bad time.
You may also inadvertently set off a signal for Queen Chrysalis to attack you or something.
Step 3: Procedure
Pretty simple actually.
Clamp your PCB in a vice (or lay it down so that it's elevated with the components face down)
Just find the component you want (in my case, i found a cool op amp)
Locate the pins on the PCB (the little silver hershey kisses on the back of the pcb, those are solder dots)
Aim the heat gun at the solder dots that hold the component in place
Use the tweezers to wiggle (wiggle wiggle) the component out of its PCB prison
Tah-Dah! You found _insert_component_here_ !
Step 4: Pros and Cons of This Method
Pros: within 5 mins, I got a lot of components out. The pic I'm showing includes some electrolytic caps, ceramic disc caps, a random resistor, a crystal oscillator (oooh, shiny), 2 op amps, some kind of transistor, a fuse (i think), and an AC capacitor.
Cons: the heat gun will destroy the circuit board. DO NOT USE THIS IF YOU ARE PLANNING TO REUSE THE BOARD. HOWEVER, if the board is just collecting dust and has no actual use, go right ahead! (the pic i show is some smoke that comes as a result of the board being burnt)
We have a be nice policy.
Please be positive and constructive.
