Shenzhen pcb prototype manufacturer – Huaqiang PCB

Shenzhen Huaqiang Jufeng Electronic Technology Co., Ltd. (Huaqiang PCB) was established in Shenzhen in 2011. The company specializes in the manufacture of 2-16 layers of printed circuit boards, and it is China’s leading prototype pcb assembly manufacturer and small batch circuit board supplier. The company has always been the service concept of producing the best quality products at the fastest speed. In 2020, Huaqiang PCB invested tens of millions to introduce advanced equipment and strictly control production standards to ensure that the products shipped are of Seiko quality. After two years of development, Huaqiang PCB company has grown rapidly in scale, and its prototype and small batch shipment capacity has reached 1,000 models/day. The company’s products are applicable to a wide range of fields, including communications, medical equipment, industrial control products, aviation, military products, test instruments, automobiles, computer peripheral products, consumer electronics, and colleges and universities and other technological fields. FS Technology believes that it can be used as the face of Shenzhen PCB manufacturing industry, so it is placed first in the list of printed circuit board manufacturers. The following are its project capabilities:

Imposition, ConcatenationZero Gap ImpositionImposition is shipped, and the gap between the intermediate board and the board is zero 
Imposition with GapsThe gap of the imposition with gap should be greater than 1.6mm, otherwise it will be difficult to edge the gong, which will affect the efficiency. 
Stamp Hole ImpositionStamp hole 0.5mm diameter, 0.3mm edge spacing 
Conventional 5-7 holes in a group

PADSCopper ProblemThe factory defaults copper in Hatch mode. It is recommended to note the copper plating method before placing an order. 
2D LineEffective lines cannot be placed in the corresponding layer as 2D lines, and Huaqiu Circuit does not process 2D lines. 
Altium Designer    ProtelVersionThere is a missing element problem in the output gerber of different versions of Altium Designer. Please note the version number when placing an order. 
Board Foreign ObjectIf components are placed far away from the PCB board, the conversion process cannot be output due to too large size boundaries. 
Window ProblemPlease do not mistakenly place the windows of the Solder layer on the paste layer. Huaqiu Circuit does not deal with the paste layer. 
Copper ProblemFill copper, if there are too many Fill blocks, the output file block will be lost. Suggestion: Use Polygon Pour for copper.
