A PCB assembler is a key figure in the electronics manufacturing industry. These professionals or companies specialize in building electronic devices onto printed circuit boards (PCBs) using various techniques such as surface mount assembly (SMT), plated through-hole technology (PTH), and electro-mechanical assembly.
Key Responsibilities of a PCB Assembler
Reading Wiring Diagrams: Understanding and following wiring diagrams to replicate pathways on PCBs.
Component Selection: Choosing appropriate electronic devices for connection to the PCB.
Manual Tools Usage: Employing hand tools, such as soldering kits, to construct and finish the PCB.
Wire Manipulation: Safely handling wire leads by twisting, stripping, bending, soldering, and crimping.
Press-Fitting Electronics: Ensuring secure placement of electronic components onto the PCB.
PCB Assembly Process
The PCB assembly process at CEN Electronic involves high-tech machinery, powered hand tools, and skilled manual labor. Our PCB assemblers carry out the following steps:
- Solder Paste Application: Applying solder paste to connection sites using a solder screen. For some projects, wave soldering provides the paste.
- Pick and Place: Machines position components onto the PCB accurately.
- Soldering: Various soldering machines, including wave and reflow soldering, secure components.
- Inspection: Conducting manual or automated inspections to ensure component placement accuracy.
- Testing: Ensuring the product functions correctly before distribution.
- Feedback: Receiving feedback from supervisors to quickly catch potential flaws.
Techniques for PCB Assemblies
Surface Mount Assembly (SMT)
The SMT method involves feeding the pick and place machine with components, programming it for the desired functionality, applying solder paste using a stencil printer, and then using reflow soldering to lock the components in place.
Plated Through-Hole Technology (PTH)
PTH involves using holes that pass through the board, with components inserted into these holes and soldered in place. This technique is suitable for boards with components requiring strong mechanical bonds.
