The metal backplane is what we usually call the metal shell or chassis. The casing usually refers to the casing used by various electronic products. According to the purpose, it can be divided into: computer casing, TV casing, mobile phone casing, instrument casing, motor casing, micro-motor casing, etc. According to the material, it can be divided into plastic case, alloy case, composite material case, etc.

The metal shell has the advantages of dirt resistance, strong metal texture, good sealing, better sound quality, strong plasticity, oxidation resistance, low processing difficulty, short construction period, and cost saving; while the aluminum alloy has the advantages of long mold opening time and slow processing speed, which leads to increased production. cost;

The backplane has always been a specialized product in the PCB manufacturing industry. The backplane is thicker and heavier than the conventional PCB, and its thermal capacity is correspondingly larger. Due to the slower cooling rate of the backplane, the length of the reflow oven is increased. It also requires forced air cooling at the outlet to bring the backplane temperature down to a level safe for operation.

Matters needing attention in the design and processing of the backplane:

1. The choice of plate and plate is very important, which will directly affect the thickness and size of the back plate. If the thickness and size are required, then the requirements for the plate are also different.

2. Thickness, the thickness of the back plate is thicker than that of the conventional plate.

3. Size, the size of the backplane is much larger, which also has a certain impact on production.

4. Drilling, due to the increase in thickness and the use of crimping devices, there are certain requirements for the accuracy of drilling.

5. Wiring planning, the backplane wiring density is relatively small, but there are special requirements for impedance requirements and inner layer circuits.

6. Surface treatment, due to the relatively large thickness and size of the backplane, some surface treatment processes are difficult to achieve.

JAVA Metal can provide the customised processing services of cold-rolled plate, hot-rolled plate, galvanized plate, copper plate, aluminum alloy, stainless steel and other materials.
