Through-hole PCB Assembly Process


What is a through-hole PCB assembly?

Through-hole PCB assembly is a method for producing electronic circuits in which the components are installed through leads. It refers to the mounting process that inserts the leads to the drilled holes and solders the components on the board by wave soldering or manual soldering.

Over time, PCB design moved from single-sided boards to double-sided boards, then came the multi-layer boards. Through-hole PCB assembly is difficult to meet the requirements of modern electronics. Nowadays, SMT technology has largely replaced through-hole construction in PCB manufacturing. But through-hole PCB assembly is still irreplaceable in some applications, such as electrolytic capacitors, connectors, and large transformers.

Through-hole PCB Assembly Process

Manual Insert line or Automatic Inserter➡Wave Soldering Machine or Selective Soldering Machine➡Out feed Conveyor

Manual Insert line can sit 2-3 workers, manually insert the THT components to the bare PCB, If THT components on the PCB is few, less than 20 kind, Can use manual insert line, use 7 workers to do this job, each worker insert 2-3 kind THT components.
