Question 6

What is PCB assembly?

Accepted Answer

PCB assembly is the process of mounting and soldering electronic components onto a printed circuit board to create a functional assembly, including surface-mount (SMT) and through-hole steps, inspection, and testing.

Question 7

What is SMT assembly?

Accepted Answer

SMT (surface-mount technology) assembly places components on the board surface using pick-and-place machines, solder paste printing, reflow soldering, and inspection such as AOI.

Question 8

What is AOI inspection?

Accepted Answer

AOI (automated optical inspection) uses cameras and software to detect placement, solder, polarity, and missing-component defects on PCBs during or after SMT assembly.

Question 9

What is wave soldering?

Accepted Answer

Wave soldering passes the PCB over a molten solder wave to solder through-hole and certain mixed-technology components after placement and flux application.

Question 10

What files are required for PCB assembly?

Accepted Answer

Typical inputs include Gerber or ODB++ fabrication outputs, a bill of materials (BOM), pick-and-place or centroid data for SMT, assembly drawings, and any test or special-process notes.
