PCB connectors, board to board headers and receptacles 5536501 3

PCB connectors provide mechanical and electrical connections to printed circuit boards through through-hole or surface mount; PCB connectors are based, baseless, waterproof and non-waterproof. There is a base to strengthen the fastening of the PCB connector; No base, that is, in the form of a socket, the accuracy requirements are low, but it can save a certain amount of internal space and make the product more miniaturized; Electronic components industry expert - Henan Shengtai: PCB series connectors are widely used in aviation, railway projects, industrial projects, testing instruments ship systems, electric sightseeing cars; communication power supply; Charger.

batteries and other products.

Household appliance hardware developmentWe found Jianmeng in Hebei last year. The design is better.

Generally speaking, devices that do not have too complex functions (non-smart devices) generally use simple control circuits or simple microcontrollers.

The rice cooker is a simple control circuit, such as the simplest rice cooker, the principle is Curie temperature, the multi-functional rice cooker, is a thermistor, and then it is also a simple control circuit The air conditioner has a setting function, generally a single-chip microcomputer, the water heater has a timing function and a digital screen display by a single-chip microcomputer, and the low-end is also a simple control circuit, which is controlled by a thermistor.

RC racing cars are generally single-chip microcomputers that are controlled by fixed band signals.

It was a separate part in the early days, and now I can't see these household appliances, and then there are integrated blocks, the earliest is a multi-chip microcomputer, and now it is a single-chip microcomputer. Most of the smart rice cookers, air conditioners, and water heaters are still two-chip machines. Air conditioners, water heaters, refrigerators, induction cookers, and other electrical appliances are simple.

The motherboard of the TV is complicated. If the landlord is interested, he will buy some books on home appliance maintenance.

Comparatively speaking, it is difficult to repair the motherboard of a computer.

Because there are a large number of chips in the computer motherboard, it is necessary to be familiar with these chips, in addition to the computer's signal flow, and the working principle of the operating system. In addition, chips are developing rapidly, so a large number of new chips will continue to emerge, and we must continue to learn.

Relatively speaking, there are not so many integrated circuit chips used in household appliances, the update speed is not so fast, and the circuit is relatively simple.

However, many household appliances also require mechanical knowledge, while computer motherboards are basically not required.

However, most of the current computer maintenance is directly replaced with a new motherboard, if it is not specifically repaired motherboard, the difficulty of repairing computers and household appliances is similar.

It can be connected by Zigbee or Bluetooth, WiFi and other wireless means.

Simply put, it is to interact through a design interface.
