Do you know the basics of these PCBA boards?

There are many differences between PCBA board and PCB circuit board, whether it is electronic components or processing process, there are more or less differences. Today we will introduce the basic knowledge exclusive to PCBA board!

The three-in-one board is a kind of lithium battery protection in order to save costs.
Basic functions: overdischarge, overcharge, overcurrent, short circuit, undervoltage
Because all functions are controlled by a single IC, if this IC is broken, it may cause the PCBA board to lose control. That is, during the charging process, if the IC is broken, the line may still be connected. Without IC overcharge protection, the power supply will still be charged when it is fully charged, which will cause the battery to overcharge, heat up the battery, and even cause serious damage. Burning or explosion of the battery.

The PCBA with lithium battery protection is equivalent to double protection for the lithium battery of the PCBA circuit board in the circuit.
Basic functions: overdischarge, overcharge, overcurrent, short circuit, undervoltage
In other words, when the big IC is broken, the two small ICs can control the entire circuit. After the power supply is fully charged, the line will be disconnected to play a protective role. Avoid hurting people and greater losses.
Leftover material with lithium battery protection board
The so-called leftover material is the waste material discarded by the placement machine when mounting the PCB, or the waste material removed during the repair process. These waste materials are not "waste", they can all be recycled and reused!
Ordinary single section board
The input voltage is generally 5V, and the current is 1A (±200MAH)
The output voltage is generally 5V, and the current is 1A (±200MAH)
Ordinary single-section boards These are the little knowledge about PCBA boards. From many details, most of them are protecting lithium batteries, protecting the safety of the circuit board and even the safety of the entire electronic equipment, in order to prevent some irreversible safety accidents. .
