2019-2-27 · PCB generally consists of four layers, which are heat laminated together into a single layer. The material used in PCB from top to bottom includes Silkscreen, Soldermask, Copper and Substrate.
2019-2-25 · Confronted with so many types of surface finish on PCB pad or land, how should we select the best type of surface finish for our PCBs? This article is a comprehensive guideline for you to refer to.
Automated Optical Inspection (AOI) AOI is used to inspect the inner layers of a multi-layer PCB prior to laminating the layers together. The optics along with the board data are used to find possible shorts or opens in the copper features that will prevent problems once the inner layers are laminated together.
There is a misperception that copper weights offer certain exact thicknesses and that these do not reduce during the production of a PCB. For example 1 oz. = 35um or ½ oz. = 18um.
Multilayer printed circuits consist of four or more circuit layers bonded together by a thickness of insulating material called prepreg and core.
