PCBA Tech - How to test the first piece tester in PCBA manufacturing?

The first article detector system (first article inspection) manufactured by PCBA in PCBA manufacturing workshop is mainly used to realize the first article inspection and refueling inspection of component resistance, capacitance and inductance on PCB circuit board. The first article inspection system is divided into BS and CS. The BS mainly includes system management, master data management, report and other modules. It is a web-based PCBA manufacturing first article management system designed for the roles of department heads and R & D personnel; The CS end mainly includes modules such as first article inspection and refueling inspection of PCBA manufacturing technology production line. It is a single-machine semi-automatic PCBA manufacturing first article inspection system specially provided for PCBA manufacturing technology testers.

PCBA manufacturing first piece tester can also detect the first piece PCB board of PCBA manufacturing technology equipment, such as solder paste board (printed solder paste re pasting element), adhesive board (double-sided adhesive re pasting element), red adhesive board (printed red adhesive re pasting element), etc. the detection types cover data errors such as wrong BOM dosage, repeated position, missing definition of XY coordinate, multi definition, multi pasting, missing parts, wrong parts Reverse, rollover, rotation and other technological problems also include the electrical performance of components such as electric bank, capacitor and inductor (usually incoming material error).

PCBA manufacturing first article tester can also test PCBA manufacturing patch components. The first article machine is mainly divided into two parts:

1. For components with silk screen printing, silk screen printing comparison can be carried out directly without PCBA manufacturing manual discrimination one by one, so as to realize the effect of batch rapid detection and improve work efficiency;

2. For the resistance capacitance without silk screen printing on PCB circuit board, the digital bridge is used for clamping detection, and the first piece machine automatically grabs the value, compares and judges it automatically. And the bridge of the first machine belongs to the custom bridge, which adds the function of testable led.

PCBA manufacturing intelligent first article inspection equipment of patch processing plant can also detect the following contents:

1. Solder paste board (printing solder paste re pasting element), adhesive board (double-sided adhesive re pasting element) and red adhesive board (printing red adhesive re pasting element) of PCBA manufacturing technology equipment.

2. The resistance and capacitance on PCB circuit board are measured through LCR bridge.

3. Electronic components IC and other silk screen elements on PCBA circuit board are detected by optical automatic comparison.
