Soldering Circuit Boards

Soldering Circuit boardSoldering Circuit Boards is a basic skill for electronic engineers,Several Tips you should know how to solder a circuit board .

1. You need prepare one solder iron ,There are lots of choice in the market , even you can buy one from amazon .


Use a soldering iron with the appropriate heat control.

2. Solder wire of an appropriate alloy.  Suggest Lead-free Tin wire , you can choose the wire thickness basing on your components , 0.8mm or 1.00mm is normal to use , and also you need consider tin wire is a clean stype or no-clean flux.

3. If possible, get flux-cored wire

Flux is an additive in solder that facilitates the soldering process by removing and preventing oxidation and by improving the wetting characteristics of the liquid solder. There are different types of flux cores available for solder wire.


4. Get PCB Circuit boards and electronic components .


5.Buy clamp to hold the components


When you prepare all those , then you can start Soldering Circuit Boards ,If you only do prototype PCB assembly , you can solder circuit board yourself , If more PCB boards, we suggest you choose one PCB Assembly manufacturer like Rayming to help you , Who can control your assembly quality .


Soldering is one of the most fundamental skills needed to dabble in the world of electronics. The two go together like peas and carrots. And, although it is possible to learn about and build electronics without needing to pick up a soldering iron, you’ll soon discover that a whole new world is opened with this one simple skill. We here at RayMing believe that soldering should be a skill in everyone’s arsenal. In a world of increasing technological surroundings, we believe it is important that people everywhere be able to not only understand the technologies they use everyday but also be able to build, alter, and fix them as well. Soldering is one of many skills that will empower you to do just that.


Soldering to a circuit board can be tricky: Too much heat can make the copper trace lift right off the board substrate. Use a soldering iron rated at 15-25 watts, no more.

Start by lightly scrubbing the board surface with a typewriter eraser to clean the copper until it's bright and shiny. Like any electrical connection, use only 60-40 rosin-core solder, preferably in a gauge close to the size of the lead you're attaching. Insert the wire or component leads into the board from the rear, and bend them over enough to keep the component from falling out.


Lightly touch the tinned soldering guy to the copper trace and the lead at the same instant. A couple of seconds later, touch the lead with the end of the solder, adding just enough solder to make a puddle, but not enough to make a fat blister. The solder needs to wet the lead and the copper trace.


Quickly withdraw the soldering iron and the solder. Don't disturb the board until well after the solder has cooled enough to freeze, which should only be a few seconds if you've used the appropriate amount of heat.
