Reasons and solutions for PCBA circuit board processing and throwing materials

PCBA circuit board processing is an indispensable step in the design and production process of Electronic equipment. PCBA circuit board carries the control system of electronic equipment. Its quality directly affects the operation of electronic equipment and product quality. A good product is inseparable from The support of high-quality PCBA circuit boards, and in the process of PCBA circuit board processing, it is inevitable to encounter some problems. Let’s take a look at the reasons and solutions for PCBA throwing materials.

PCBA circuit board processing is an indispensable step in the design and production process of electronic equipment. PCBA circuit board carries the control system of electronic equipment.

A good product is inseparable from The support of high-quality PCBA circuit boards, and in the process of PCBA circuit board processing, it is inevitable to encounter some problems. Let’s take a look at the reasons and solutions for PCBA throwing materials.

Reasons and solutions for PCBA circuit board processing and throwing materials

Reason 1: The problem of the suction nozzle, such as the deformation, blockage, and damage of the suction nozzle, causes insufficient air pressure and air leakage, which causes the material to be sucked and the material to be taken incorrectly. The identification fails and the PCBA is thrown.

Countermeasure: Clean and replace the nozzle.

Reason 2: There is a problem with the feeder, the setting of the feeder is incorrect, the position is deformed, and the feeding mechanism is not good, resulting in insufficient or poor reclaiming and PCBA throwing.

Countermeasure: reset the feeder, clean the equipment, calibrate or replace the feeder.

Reason 3: Problems with the identification system, poor vision, unclean vision or laser lens, foreign objects interfere with identification, improper selection of identification light source or insufficient intensity and grayscale, or the identification system may be broken.

Countermeasures: Clean and wipe the surface of the identification system, keep it clean without foreign objects, oil pollution, etc., adjust the intensity and gray level of the light source, and replace the parts of the identification system.

Reason 4: Position problem, position deviation, the suction nozzle is not in the center of the material when picking up the material, and the height of the material is incorrect (generally, it is subject to the pressure of 0.05mm after touching the part), which causes the deviation, the material is not taken correctly, and there are Offset, when it is recognized, it does not match the corresponding data parameters and is discarded by the recognition system as invalid material.

Countermeasures: Adjust the reclaiming position, height and other parameters.

Reason 5: Vacuum problem, insufficient air pressure, unsmooth vacuum air pipe passage, foreign matter blocking the vacuum pipe, or vacuum leakage caused the air pressure to be insufficient and the material cannot be taken out or dropped on the way to paste after picking up.

Countermeasures: adjust the air pressure steep slope to the required air pressure value of the equipment (generally, the placement machine requires 0.5~0.6Mpa), clean and dredge the air pressure pipeline, and repair the leaking air path.

According to relevant research, static electricity is also a cause of PCBA material throwing, so the placement machine should be well grounded, and anti-static work should be done on the production site.

It is normal for the placement machine to have PCBA throwing, but if the PCBA throwing rate is high, it will seriously affect the production efficiency and production cost, which must be solved. When there is a serious PCBA throwing phenomenon, you can ask the on-site personnel first, through the description, and then according to the above seven reasons, observe and analyze directly to find the problem, so that the cause can be more effectively found and solved, and the production efficiency is improved. , but take up too much machine production time.
