The Processes of Through-Hole Technology PCB Layout
Component Placement: Through-hole technology for PCBA means that the engineer begins to install a component in a certain position depending on the PCB design files.
Inspection and Rectification: Once all of the components of the circuit are positioned, an inspection of the board is made. The inspection checks whether the components are correctly positioned. If in this step the components are identified to be placed wrongly, issues like these are corrected during the rectification process. When the purchaser uses this method, inspection, and rectification of defects must be made before the soldering process.
Soldering: The following step after that is soldering, which affixes the components placed to their respective pads of an integrated circuit.
Testing: When the PCBA Assembly China and soldering activity is done, there is usually a testing of the board done. All of the PCB boards that are commonly used in electronic devices have been through this process and tested.
Soldering Techniques
Wave soldering– Wave soldering is a process whereby a PCB passes over a wave of hot soldering liquid which solidifies the components. It is the most often employed method of THT and SMT PCBA.
Braze soldering– like other kinds of soldering, is a process whereby parts are joined by heating. This technique again, melts the metals at the bottom for fitting the filler metal sufficiently. Braze soldering applies the highest temperature in its process and gives the most favorable joint result.
Reflow soldering- This is a process of soldering where the components are joined with the board with solder paste that has been heated. In its liquid form, the soldering paste joins the pads and the pins in the fabrication of PCB.
Soft soldering– In the method used here, a metal space filler that is tin-lead alloy is melted using an electric torch or gas to fit the components into the board. The soft soldering process is common in the assembling of small, delicate items onto a printed circuit board.
Hard soldering– Hard soldering is used when joining copper, brass, silver, or gold at a temperature of approximately 300 degrees Celsius. In comparison to soft soldering, hard soldering yields a higher standard of joining a metal to another metal.
As a start in the electrical and electronic PCBA Assembly China and soldering processes of printed circuit boards, you may use PCB design software. The tools are something like the comparison between the schematic view which is also known as the top view of the component and it has some of the features for the schematic drawings which are used along with the circuit layouts, is easy to manage data in a single window and for circuit analysis as well.
