PCBA processing after welding reasons: one, the component plug-in close to the process side of the component plug-in position, two, the customer has special requirements of high sensitivity components, can not over wave soldering, three, components over t
Whether in the manufacturing and assembly process or in actual use, PCB to have reliable performance, this is very important.
Harm of PCB board deformation: on the automatic surface mounting line, if the circuit board is not smooth, it will lead to inaccurate positioning, components can not be inserted or installed in the hole of the board and surface mounting pad, and even dama
Considerations for PCB design are analyzed below: from schematic creation of component parameters to PCB design process -> Input schematic netsheet -> Design parameter setting -> Manual layout -> Manual wiring -> Verify the design -> Aud...
Keyou circuit is a professional production of high precision double-sided multilayer circuit board, module gold circuit board, car circuit board, car charging circuit board, traffic recorder,COB power supply, computer motherboard, medical circuit board, m
Common causes of PCB line break: 1, film process: 2, exposure process: 3, development process: 5, electroplating problems
PCBA processing to avoid PCB board warping method:1. Reduce the influence of temperature on plate stress; 2. Adopt high Tg plate; 3. Increase the thickness of the circuit board, 4. Reduce the size of the circuit board and reduce the number of pieces of th
The production of Keyou circuit cannot be separated from your design. All engineers please design according to the detailed production process of conventional production.
The method of high-speed PCB design and wiring to solve signal crosstalk: First, in possible cases to reduce the signal along the conversion rate usually in the device, while meeting the design specifications as far as possible to choose slow devices, and
This article focuses on conductive holes, keyholes, and the connection between Protel 99 SE/pads/ and CAM350 geber files Conductive holes: via keyholes: pad is particularly prone to several problems
The plug technology meets the following requirements :1. Copper can be found in the through hole, but the plug cannot be used for resistance welding. 2. There must be tin lead in the through hole, with a certain thickness requirement (4 microns). Do not a
For you to analyze the common rules of thumb in PCB design wiring: first, vertical wiring, second, heat dissipation hole, third, right Angle wiring
