Halogen-free PCB printed circuit boards have low water absorption and meet the requirements of environmental protection, in other performance can also meet the quality requirements of PCB board.
Why is lead not allowed on printed boards, assembly processes and products? There are two reasons for this: first, lead is toxic and affects the environment; Second, leaded solder is not suitable for new assembly technology.
At present, the technology of metal extraction and recycling in waste printed circuit boards has been relatively mature. However, there is the problem of recycling the large amount of metal that remains after extraction.
The interconnection of various plates in electronic facilities often requires the use of PCB plug sockets with spring contacts and a matching preset printed circuit board with connected contacts.
Usually does not contain volatile solvent, low temperature fast curing, can meet the requirements of mass production automation, high production efficiency, good product quality, heat resistant curing flux accounts for more than ten energy.
Other features are also available, including crimping pins, graphic overlays, laser cut grooves, carved flexible circuits, shields, flexible heaters and stiffeners. With so many possibilities, there is a flexible circuit board to suit every need.
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
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.
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
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 this way, the printed circuit or printed circuit of the finished board called printed circuit board, also known as printed board or printed circuit board.
Kingford is a PCB company engaged in the production and assembly of circuit boards. We not only sell PCBA, but also have many strategies related to PCB design and PCB proofing. Next, let me introduce you to some matters related to PCB.
