Pcb driver circuit board
One is the finished board and one is the bare board
PCB(Printed Circuit Board) is called "Printed Circuit Board". Made of epoxy glass resin, PCB is divided into four, six and eight layers according to the number of signal layers.The chip and other SMT elements are attached to the PCB.
PCBA may be regarded as the finished circuit board. PCBA cannot be counted until all the processes on the circuit board are completed
That is to say, PCB empty plate goes through SMT upper part, and then goes through the whole process of DIP plug-in, namely PCBA
Printed circuit Board (Printed circuit Board) : Printed circuit Board: Printed circuit Board: Printed circuit Board: Printed circuit Board: Printed circuit Board: Printed circuit Board: Printed circuit Board: Printed circuit Board: Printed circuit Board: Printed circuit BoardThe electrically conductive graphics that provide electrical connections between components on an insulating substrate are called printed circuits.In this way, printed circuit or printed circuit board, or printed circuit board or printed circuit board.
The standard PCB has no parts on it and is often referred to as the Printed circuit Board Printed Wiring Board (PWB)
PCB has many names, which can be called circuit board, circuit board, printed circuit board, etc. PCB is an important electronic component. As a bare board, PCB is used to attach electronic components, making them connect with the circuit board and realize certain functions.
PCBA is the abbreviation of Printed Circuit Board Assembly, but in foreign countries, PCBA is generally translated into PCB Assembly.PCBA is a finished product of PCB bare board after SMT patch, DIP plug-in, PCBA test, quality inspection and assembly.It can realize the designer's design function. Almost all electronic products, such as smart home, AR, VR, medical equipment, etc. need to use the PCBA board.
PCBA, short for printed circuit board assembly, usually means to insert corresponding components (such as resistance, capacitance, IC, etc.) on the circuit board and deliver them to the customer!
PCB is short for circuit board!Usually means a circuit board without any components!
Power on, measure the ground voltage of the power supply end and signal end of the receiving head with the multimeter dc stop. The normal value shall be the voltage of power supply pole +5V and the voltage of signal pole + 2.5v.Otherwise abnormal.Common failures include receiving head damage or capacitor breakdown.
The simplest distinction is that one is a semi-finished product and one is a finished product, PCB is a semi-finished product, PCBA is a finished product, pasted piece, first there is PCB before there is PCBA, PCBS with good paste can be used directly
