| Message: | Shenzhen Jie Du State Technology Co., Ltd. focus oncustom PCB assembly,PCB prototype manufacturer,PCB Assembly Manufacturer,PCB Prototype Factory and other areas of service. We alway adhered to the business philosophy of "Customer first, Keep improving"and focus on supplying the electronic PCB assemblyx19b65aan with highest quality . Shenzhen Jie Du State Technology Co., Ltd. is specialized in Industry and agriculture,Electronic Component,PCB circuit board since established in 10 years ago.So far,our company has established its branch companies in major cities throughout the country.Formed in Guangdong Province,Shenzhen City,Futian district,Futian Road, Futian District, Shenzhen, China as the center, the radiation sales system and service network.Details: PCB Assembly Design in different stages need to set up different points in the layout phase can be used to carry out large grid layout of the device; For IC, non-positioning connectors and other large devices, you can use 50 ~ 100mil lattice precision layout, and for resistive capacitors and inductors and other passive small devices, can be used 25mil grid points for the layout. The accuracy of the grid is conducive to the alignment of the device and the appearance of the beautiful. PCB layout rules: 1, under normal circumstances, all components should be arranged on the same side of the circuit board, only the top components too dense, in order to some limited and small heat of the device, such as chip resistors, chip capacitors, paste Chip IC on the bottom. 2, in ensuring the electrical performance of the premise, the components should be placed on the grid and parallel to ea |
