How to choose the base material of PCB board
PCB circuit board with insulation board as the base material, cut into a certain size, it is accompanied by at least one conductive graphic, and cloth holes (such as component holes, fastening holes, metallization holes, etc.), used to replace the chassis
Summary of practical tips for high frequency PCB board design
The above is for everyone to share the PCB board interconnect high frequency PCB design skills, if you are familiar with these methods, you can understand the use of back copper-covered coplanar microstrip design than strip line design is more economical
Smart bracelet PCB board design precautions
A smart bracelet is usually composed of a radio frequency circuit unit, a clock circuit unit, a memory circuit unit, a sensor circuit unit and a main control MCU unit, etc., and the circuit PCB is usually concentrated in a small range, single-sided or dou
Five key points of PCB board design
PCB circuit board is the basic electronic components of all electronic circuit design, and the design of PCB circuit board is also a must understand for makers. The role of PCB is not only to combine scattered components, but also to ensure the regularity
What does a multi-layer PCB look like? High-end PCB board design process
Layout engineers think about it! No longer afraid of not painting!Think about purchasing want to cry, more than 10 times more expensive than ordinary through hole plate! Therefore, only products like the iPhone are willing to use. Other phone brands, no o
PCB board common bad cause analysis
Physical changes in the fibre-forming layers of stained glass, such as separation between layers.However, this situation is not a poor solder joint, but the substrate is too hot, reduce the preheating and solder temperature or increase the substrate trave
PCB board through hole plug function and process introduction
Prevent the surface solder paste from flowing into the hole to cause virtual welding, affecting the mounting. 5. Prevent the tin bead from popping out during over-wave soldering, resulting in short circuit. The realization of the plugging technology of co
PCB board bending and warping causes and improvement measures
Control welding temperature and time: In the welding process of the PCB board, the welding temperature and time should be controlled to avoid excessive heating or heating time is too long, resulting in bending or warping of the plate
PCB board warping prevention methods
The method of baking board is: conditional PCB factory is to use a large oven baking board. Before putting into operation, a large stack of copper clad plates is sent into the oven, and the copper clad plates are baked for several hours to ten hours at a
The basic steps of PCB board CAM production
Each PCB board is basically composed of the aperture hole layer, DRILL layer, line layer, solder mask layer, character layer, in the CAM350, each load layer will be separated by a different color, so that we can operate.
PCB board production wastewater pollutants and PCB board design wastewater treatment
The production process and chemical solution of different PCB design manufacturers are still very different. Before the design of the wastewater treatment project, participate in the waste water diversion work of PCB board design and production, and verif
