PCB Base Material

Selecting the surface finish and getting the design optimised are important steps in ensuring that your product performs well, but is that the end of the process? No, you also have to ensure that the material specified is available within the factory and that the factory is UL approved to support such materials.

PCB Assembly AOI

Automatic Optical Inspection Automated Optical Inspection, also called Automatic Optical Inspection, abbreviated as AOI, is well responsible for quality control in terms of both Printed Circuit Board (PCB) fabrication and PCB Assembly. AOI system will identify the following types of unacceptable deviations: Wrong components Twisted/turned components Tombstoning” (where the component is situated like a tombstone) … Continued

PCB Surface Finishes

A surface finish can be either organic or metallic in nature. Comparing both types and all available options can quickly demonstrate the relative benefits or drawbacks. Typically, the decisive factors when it comes to selecting the most suitable finish is the end application, the PCB assembly process and the design of the PCB itself. Below … Continued
