In the printing industry, photo platemaking is often used to produce pictures on paper. That is, by taking photos, the picture of the bottom plate, etched on the copper plate or zinc plate, with this copper plate or zinc plate, you can print a lot of pict
Basically, the goal of setting up the test area is to test the components on the circuit board for specification and weldability.
The manufacturing process of printed board is still more complex, to go through the light painting, photographic plate and other chemical processes, consume more materials, longer cycle, high cost.
Although the miniaturization trend makes it more challenging, it is possible to use multiple connector groups on two PCB boards by using best design practices.
In the core structure, all the conductive layers in the circuit board are coated on the core material; In the foil-coated structure, only the internal conductive layer of the circuit board is applied to the core material, and the external conductive layer
general solid insulation material is not easy to fill the dead corners, and where the need to be closely matched, such as high-voltage cables, transformers, small capacitors, can be filled with mineral oil, ethylene glycol and carbon chloride, as liquid i
Sunblock welding process can be roughly divided into three operating procedures:The first step is exposure. The second step is developing. The third operation process repair board.
In production, we will have the engineering review and approval of your information, if there is a problem the first time to combine with you! In order not to delay your time, the combination form you provide must be accurate.
Copper clad plate is the basic material of electronic industry, mainly used in the processing and manufacturing of printed circuit board (PCB), widely used in TV, radio, computer, computer, mobile phone, communication and other electronic products.
The PCB layout determines the performance of a switched power converter. You don't have to spend countless hours debugging EMI, noise, signal integrity, and other issues associated with poor layout.
In addition to the machining technology, back drilling design and stump control also have some effects on PCB loss.
Poor insulation of copper wire will lead to arc between copper wire and copper wire. Too close between the copper trace and the path, it is easy to short-circuit risk; The lack of thickness of the circuit board can lead to bending and breaking.
