Three key points to note when drawing highquality circuit boards
PCB（printed circuit board）designis based on circuit schematics to achieve the purpose and function required bycircuit designers, drawing design needs engineers to accumulate years ofexperience, then want to draw high-quality circuit boards need to pay attentionto the following aspects:
1: padoverlap technology, pad overlap indicates the overlap of the hole, in the drillingprocess, due to multiple drilling in the same location, the drill bit will bebroken, thus damaging the hole, which circuit board manufacturers have betterproducts, must check the overlap of the hole layer by layer.
2:surface mount equipment pad technology, surface mount equipment pad technologyfor continuity testing, for very dense surface mount equipment, the distancebetween its two feet is very small, his pads are also very thin, loaded testpins, they must be staggered up and down to ensure the high quality of the PCBcircuit board, in has passed the quality certification of the circuit boardmanufacturer, his surface mount equipment pad is not too short.
3: Thedesign of the electrical ground, in general, a good reputation, good service circuitboard factory will be designed for the electrical ground in the form of flowerpad power, ground layer and the actual printed circuit board on the oppositeimage, all connections are isolated lines. By the way, when drawing multiplesets of power lines or ground isolated lines, do not leave gaps, otherwise itwill lead to a short circuit between two sets of power supplies, which isunlikely to cause, the connection area is blocked.
As PCBcircuit boards are very important for the assembly configuration of electronicproducts, good circuit board companies have strict requirements for the qualityof the circuit board factories they use. Consumers are advised to choose PCBcircuit boards first from circuit board manufacturers who have been certified forquality and who can ensure that they can buy boards that meet both nationalrequirements and their own, aspiring to a high quality PCB circuit boardproducts. Highly recommended to try Shenzhen BQC Electronics Co., Ltd, BQC is amanufacturer of industrial grade product circuit boards that integrates PCBdesign, PCB prototyping small to medium volume production, PCBA processing,component BOM matching and stencil making with special attention to the qualityof the circuit boards.
