PCB materials have incomparable advantages compared with other materials. Suitable for power component surface mount SMT public art. Without heat sink, the volume is greatly reduced, the heat dissipation effect is excellent, good insulation and mechanical
PCB materials have incomparable advantages compared with other materials. Suitable for power component surface mount SMT public art. Without heat sink, the volume is greatly reduced, the heat dissipation effect is excellent, good insulation and mechanical
When the PCB enters the insulation area, the PCB and components are fully preheated to prevent the PCB from suddenly entering the welding high temperature area and damaging the PCB and components.
Soft printed board as a domestic faster growth industry, many materials and equipment still need to continue to explore, mass production also need to process and machinery equipment, material field of continuous integrity, this paper extracted a link to t
In the first manned Apollo spacecraft, for example, an electrostatic discharge caused an explosion that killed three astronauts. Electrostatic discharge (ESD) in the process of gunpowder manufacturing, resulting in explosion casualties often occur.
the components on the PCB should be evenly distributed, especially the high-power devices should be dispersed to avoid local overheating stress on the PCB when the circuit is working, affecting the reliability of the solder joint.
Pre-welding quality inspection also includes: PCB electronic assembly design audit/or review; Audit/or review of welding process plans and procedures; Identification of outsourced units such as printed boards, components, welding process materials, and ac
Single-sided circuit board is the most basic PCB circuit board, the parts are concentrated on one side, the wire is concentrated on the other side, because the wire appears on one side of the reason we call it single-sided circuit board. Because single-si
The second method is to let the designer of the circuit board factory beside a piece of copper foil around the circuit board pad, the attachment area is large, the pad is not easy to fall off, if there is no space around the pad beside the copper foil
The soft plate is also like the hard plate, and can be made of plated through holes or surface adhesive pads for through holes insertion or surface adhesive installation. The surface of the board can also be attached to a soft protective and solderproof C
FPC is a printed circuit board with high reliability, excellent bending and light weight, which can place parts and circuits and complete circuit functions based on polyester film or polyimide after a series of production processes.
When the circuit board is pressed together with the release film, the silicone oil will be transferred to the circuit board, resulting in poor binding degree, so the silicone oil on the surface of the product needs to be completely cleaned before a step p
