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.
In the environmental protection and clean zone, a number of innovative technologies and solutions applied to the "three wastes" (waste gas, wastewater, solid waste) treatment and resource recovery in the printed circuit board industry were also ...
PCB production process is more complex, it involves a wide range of processes, from simple machining to complex machining, there are ordinary chemical reactions and photochemical electrochemical thermochemistry and other processes, computer-aided design C
To sum up, to choose an excellent PCB design company, you need to consider the strength of the company, customer reputation, service quality and price, after-sales service and other aspects. In the selection, you can according to their actual needs and bu
From passive components to active components and integrated circuits, all eventually become surface mount devices (SMDS) and can be assembled by pick-up and drop devices. For a long time it was thought that all pin components could eventually be packaged
PCB assembly, do not apply any solder on the top or bottom pad. Use screws with built-in washers to achieve tight contact between the PCB and the metal case/shield or ground surface bracket.
On a mobile phone PCB board, it is usually possible to place the low-noise amplifier circuit on one side of the PCB board, and the high-power amplifier on the other side, and finally connect them to one end of the RF antenna and the other end of the baseb
Differential PCB lines are usually always routed in pairs, and the distance between them along the direction of the pair remains a constant at any position. In general, the layout of the differential pair is always as close as possible.
The automatically designed circuit board is not as beautiful as the manual design, but it can meet the specified requirements in terms of electronic characteristics, and the complete performance of the design is guaranteed.
Now PCB design time is getting shorter and shorter, smaller and smaller board space, higher and higher device density, extremely demanding layout rules and large-size components make the designer's job more difficult.
There is also a hybrid structure of flexible PCB circuit, which is also a multi-layer board, but the conductive layer of the multi-layer board is composed of different metals. Located in Carlsba, California
