Why Is Visual Inspection Important During Printed Circuit Board Assembly Processing?
Optimal PCBA manufacturing depends on effective Quality Control (QC) management. So how can you maximize your QC process? Learn why visual inspection of circuit boards is a must-helping you identify missing or misplaced components, and calculate dimensions and distances to prevent errors during electronics production.
As an experienced electronic manufacturing service provider, TECOO must monitor and control the quality of printed circuit board assembly at all times in order to achieve the best effect of circuit boards in the production of electronic equipment. In the process, people further manually check the quality of the circuit board using specific cognitive skills. For example, visual inspection after reflow oven is the second QC process in SMT production line. Each PCBA is inspected by a QC team, who are able to spot obvious defects with the naked eye, such as contaminated solder paste and missing parts. The most common visual inspection is the ability to inspect reflow solder joints by observing light reflected from a common prism from different angles, further ensuring quality from the start.
The effectiveness of visual inspection depends on the competence of the inspector, the consistency and applicability of inspection standards. Inspectors must thoroughly inspect each board for traces, solder paste conditions, component placement, etc., to ensure that all components are secured in the correct position. Visual inspection also helps ensure that all solder joints are perfectly soldered to the board and there are no electrical failures. Because some components are so miniaturized, equipment is needed to assist (microscope), which allows you to magnify the circuit board to check for quality or detect errors/defects, thereby changing electronics production settings to prevent errors.
TECOO has a professional team with more than 20 years of manufacturing experience, and its quality standard is ISO9001:2015 certified in line with international quality standards. We have extensive expertise in electronics manufacturing, whether you need prototyping, PCB assembly, small or high volume orders to respond quickly while ensuring product delivery speed, high quality and cost competitiveness.
