Testing & Inspection Capabilities

AOI (Automated Optical Inspection): This testing to check whether any components are missing, the solder paste and the polarity.

X-ray: This testing is commonly performed on Quad-flat No-lead (QFN) PCBs, and Ball Grid Arrays (BGAs).

ICT (In-Circuit Test): In-circuit testing is done to check whether there are any shorts, or opens in the circuit. Besides this, it also checks the capacitance, resistance, and other quantities to ensure that the PCB assembly is done right.

Visual Inspection: visual inspection involves a general quality check of the circuit board.

FAI (First Article Inspection): checking the first sample soldering before production run.

Functional Testing: check the functionality of the PCB, and ensure whether the performance is according to the expectations.
