What are header pins used for?
What is Pin Header Connectors? Pin header is a type of electrical connector, this connector are widely used in electronic or instrumentation of PCB (Print Circuit Board) function as bridge between two PCBs which were blocked, and used to take current or signal transmission.
How do you count pins on a connector?
Column count is simply starting at the bottom of the row on the right (female) on the left (male) and count up to the top. You then pick up the count at the bottom of the next row to the left/right and count to the top again.
What’s the best way to practice the soldering process?
The following tips will help you to practice good soldering methods: First, clean the PCB joints well using a blade or knife to remove dirt and corroded materials. If the joint is dirty, the solder joints will be loose. Clean the leads of components before placing them on the PCB.
Do you need a soldering iron to solder a PCB?
Soldering requires Soldering Iron, Soldering Lead and Flux along with a PCB and component layout diagram. Selection of the Soldering Iron is very important. Soldering Iron is the electric device that heats the solder lead and makes the joint. Many types of soldering irons are available, so select one with 15-25 watts.
What should be the angle of the soldering iron?
The soldering lead and the iron tip should be at an angle of 45 degrees so as the make the solder flow easily. Do not keep the soldering iron tip more than 3 seconds on the soldering joint when soldering CMOS components. After soldering, check the solder joints carefully.
Why do you use tin instead of lead for solder?
When you take away the lead, you also take away some of the properties of solder that make it ideal for what it was intended — joining two pieces of metal. One such property is the melting point. Tin has a higher melting point than lead resulting in more heat needed to achieve flow.
