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
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,
Analysis of the deformation causes of PCB board in the process of processing: 1. Incoming material of copper clad plate: 2. Pressing: 3. Welding resistance, character and other baking process: 4. Hot air solder leveling: 5. Storage
Single-side backwelding boards are rarely used now, because double-side backwelding can save space on the circuit board, which means it can make the production smaller.
