Why should we do electrostatic protection in PCBA processing? PCBA board has precision electronic components, many components are more sensitive to voltage. A shock above the rated voltage will damage these components
SMT proofing small batch processing said of high charges mainly refers to the loss of time, rather than start-up loss. That is to say, before SMT processing, whether it is large area SMT processing or small scale SMT processing, the preliminary work needs
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,
SMT patch processing common detection methods: 1, optical detection method, 2, artificial visual detection method, 3, AOI detection method
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
SMT patch processing common materials: 1, patch resistance, 2, patch capacitor, 3, induction coil, 4, transformer, 5, crystal diode, 6, field effect transistor
Before the production of products, the production materials must be inspected according to the inspection standards and inspection process documents to ensure the production and quality of products, at the same time, to ensure the normal supply of materia
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
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...
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
