SMT patch BOM list arrangement Note: 3. The description must be clear. 4. There are some crucial electronic components. Considering the fluctuations of the component market and the cost, 5. 6. Coordinate values required by coordinate T/B to distinguish po
There are three PCB design methods that can withstand 100A current：1: PCB wiring, 2: terminals, 3: custom copper bar, 4: special process
Small batch PCB proofing charge is high, mainly in SMT SMT processing, whether large batch SMT processing, small batch SMT processing, need to do the preliminary work is the same
Through the hole plug oil is to guide through the hole with ink inside the plug hole production, the emphasis is on the quality and tightness of the plug hole. Through the hole plug oil treatment inspection standard is or light, above must have ink cover,
It is strongly required in various PCB design guidelines that high frequency and high speed signal transmission lines need to maintain consistent characteristic impedance, and that 90° Angle routing at the corner of the transmission line will change the l
Quick solution to PCBA short-circuit problem: 1. Use short-circuit positioning analyzer for inspection, 2. Light up the short-circuit network on the PCB diagram. 3. In case of the same short-circuit in batches, take a board to operate the secant line and
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...
