Soldering an SMT MOSFET Driver with a hotplate using microcontroller




Soldering SMD components isn’t as hard as you might think. In fact it’s easy.

If you follow this instructables you’ll soon see just what great results you can obtain at home using just a hotplate.
It’s not just being able to make small circuit boards that makes SMT soldering so good it’s also a nicer way to solder. All the ‘hard’ work is in placing the components. You then only need to reflow the solder for about 5-7 minutes and your done.

No more long soldering sessions spent hunched over a hot soldering iron breathing in all those fumes.

All you need is the PCB, some solder paste, the SMD components and a hotplate.

Step: 1 Gather all the parts

Gather all the parts

Gather and identify all the parts, remove packaging and lay out ready to be placed on the board.

Make sure you know which resistor is which, they are each marked as shown.

Also ensure that the diode will go in the correct way round. The cathode, the end you want connected to the positive rail, is marked with a line.

Step: 2 Prepare the PCB

Clean the boards’ pads, preferably with isopropyl and put some flux on each of the pads. Also make sure the legs of the components are clean.

Step: 3 Apply Solder Paste

Apply Solder Paste

Using a tooth pick put a dot of solder paste on each pad. Don’t use too much and avoid splats and bridges. Less is more with solder paste.

Step: 4 Place Components

Carefully position each component (starting with the smallest) using a pair of tweezers. At this point a magnifying ring or head mounted magnifying goggles can really help.

WARNING! Make sure the diode is the correct way round and that the two resistors are in their correct positions.
