PCB Tech - The role of PCB in communication equipment

What is the use of circuit boards in communication equipment

This GT-PLC control system adopts multiple sets of CPU control. The main CPU has a very powerful operating speed and memory. It is the soul of the entire system, or the central system of the system. It has a built-in 24-bit high-speed AD conversion module, which is better than traditional The operating speed and sampling accuracy of the PLC system without or with only 8-bit\10-bit AD analog-to-digital conversion module is an order of magnitude higher.

It can obtain the high-precision and professional weighing AD module accuracy and sampling processing requirements corresponding to the weighing industry, which is unmatched by general PLCs on the market. This is also one of the important factors in the difficulty of automatic process control for general weighing instrument manufacturers.

For powder packaging equipment, many blanking control methods generally use pulses as the driving signal for controlling stepping motors or servo motors. For single-chip control, this is almost impossible to complete, because the pulse sending and It is impossible to complete synchronous communication at the same time of ADM modulus processing. According to the interrupt priority, only one can be completed before processing the next one.

For ordinary PLCs, sending pulses and processing analog-to-digital conversion at low speeds are still reluctant, and there is no way to talk about high-speed sampling. However, for our specially developed PLC, this is completely possible and has been realized! Not only can it be realized, but it can also control the output of two pulses at the same time! That is to say, two different stepping or servo motors can be controlled at the same time to do different operation postures at the same time. This is also a feature that has been professionally referred to as "bull art"!

For example, in addition to traditional photoelectric input ports, material level input ports, etc., there are also control ports that meet special equipment for special materials: leak-proof control valve ports, patented water-cooling control ports, bag holder control ports, single The feedback port of bag cancellation, the initial vibration port of the material bag can be preset according to the weight, and so on. The corresponding control device can be installed at any time when the user needs it.

For a single machine, the above is enough to meet the control needs! The important thing is that we have also reserved multiple input and output ports that need to be controlled by customers with automatic lines as the level of automation improves, which is convenient for users to upgrade in the future! Meet the needs of customers to improve the efficiency of the equipment and process in different periods!

Introduce the principles that should be paid attention to when replacing the circuit board filter

1. Pull out the exhaust filter from the oil mist separation box and replace it with a new one, ensuring that the port position is correct.

2. Under the correct conditions, the top of the central screw of the spring of the filter of the chip vacuum packaging machine should protrude from the spring for about 2-5 turns.

3. Use special tools to install the filter spring according to the disassembly steps, and then install the screws in the groove.

4. Tighten the screws on the spring of the exhaust filter to ensure that the gasket on the exhaust cover is clean and undamaged and can work normally.

5. Install the gasket, exhaust end cover and oil mist separation box in sequence, and connect the exhaust pipe of the circuit board vacuum packaging machine.

Steps of attaching the outer isolation cloth to the chip vacuum packaging machine

Install the heating strip and the partition board, connect the heating wire, and the circuit board vacuum packaging machine can be debugged and used. Oil change operation: Before changing the oil, run the pump for 15-30 minutes. After the oil temperature rises, stop the operation, open the oil drain plug to drain the oil, and then tighten the drain plug to fill with new pump oil. Specify the height. If the oil in the pump is seriously polluted, add new oil and repeat the operation to make the pump clean.

As far as the current PCB market is concerned, the chip vacuum packaging machine has been greatly popularized and has become a very common packaging equipment, especially the use of ordinary vacuum packaging machines. With the continuous use of vacuum packaging machine operators After the purchase, it is indispensable to make some settings before using it. After understanding this knowledge, you will have a new understanding of the operation of the circuit board vacuum packaging machine.

Chip vacuum packaging machines are non-standard equipment. What conditions need to be known for custom vacuum packaging machines is not known to every customer. Some customers who use vacuum packaging equipment for the first time, because of the different nature of packaging PCB products, require different packaging materials, so The requirements for the performance of PCB vacuum packaging machines are also different.
