Introduction to the product characteristics of the circuit board

Hot-pressed silica gel, gray hot-pressed silica gel, hot-pressed thermally conductive silica gel, and silica gel have good heat conduction and fire resistance properties:

This product is made of silica gel with a special heat conductive material. This product is mainly suitable for hot pressing equipment. It is placed on the bottom surface of the hot pressing head, which has a certain buffer effect on the temperature, so that the temperature is more uniform, and isolates the hot pressed product from The hot pressing head is in direct contact to prevent residual debris from the hot pressing head from affecting its flatness, and at the same time, it has an isolation protection function to prevent electrostatic leakage.

Features:

1. Silicon itself has extremely high heat transfer and buffering properties, and will not cause damage to PCB, glass, etc.

2. It has strong stability to heat.

3. It has extremely high resilience and non-adhesive properties.

Application range of hot-pressed silicone rubber, gray hot-pressed silicone rubber:

This product is especially used in the TFT-LCD assembly project, and compresses the FlexiblePCB into the Glasspannel project to play the role of heat conduction and buffering of the Heatingtool, so it will not cause damage to the PCB and Glasspannel under the action of heat and pressure in the assembly project. .

Product specifications:

1. The products are divided into anti-static (black) and ordinary (gray).

2. Common thicknesses are 0.2mm, 0.25mm, 0.3mm, 0.45mm, etc.; common lengths are 5m, 10m, etc., and the width can be customized according to customer needs.

The purpose of weighbridge remote controller circuit board

The purpose of the weighbridge remote controller is very large, almost all electronic products need to use the circuit board. So what is the difference between the circuit boards of each product? For example: Can the motherboard of a computer be used in a TV? The electronic scale remote control calibration method is basically the same as the principle steps of the weighbridge remote control. The answer is no. The circuit board has its own specifications like life, and the weighbridge controller has its own line direction.

1. Calibrate the indication error of the electronic platform scale: its allowable error is 1 division value, which is one of the main methods of weighing fraud. For some commercial weighing scales, the weighbridge remote controller only has the functions of weighing, pricing, display, and printing, which is far from enough.

2. Repeatability calibration: its allowable error is 1 division value, and the weighing and management automation are closely integrated, so that the weighing, pricing, storage, and sales management are integrated, and the management automation is realized.

3. Four-corner error calibration of platform scales (electronic scales): its allowable error is less than one division value, and the weighing system and the computer system form a complete integrated control system.

4. The weighbridge remote controller uses the strain electric measuring principle to weigh. A strain gauge is attached to the elastic body of the load cell, which can monitor the weight of the aluminum (steel) water in the aluminum (steel) ladle in a timely manner. When there is no load, the bridge is in a balanced state and the output is zero.

5. With multiple functions, high precision, strong defense, low maintenance cost, each strain gauge generates a strain proportional to the load, and the external load can be measured by the output voltage.

The above introduction of the product characteristics of the PCB board and the description of the use of the scale remote controller circuit board.
