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
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 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
Purpose and precautions of reserved process edge in PCB design: Reserved process edge is the part added on both sides or four sides of PCB board to assist patch plug-in welding, which is mainly to assist production and does not belong to the PCB board. It
PCB design layer number to consider the following problems: 1, use,2, required signal type,3, through hole type,4, required signal layer density and number,5, required plane number,6, manufacturing cost,7, delivery time,
