Prototype PCB assembly nozzle problems and solutions
The prototype PCB assembly nozzle is a tool for the SMT placement machine to pick up the chip material. In the SMT process of prototype PCB assembly, problems with SMT nozzles can result in poor placement and reduced SMT efficiency. Next, PCB manufacturers will introduce the problems and solutions of SMT nozzles in prototype PCB assembly.

Solutions |
|
Poor suction effect |
Adjust the position of the feeder, flatten the feeder, check whether the air pressure is normal, check the Z motor or reduce the speed of the motor, check the vacuum generator and its gas path, re-do the suction height, and increase the suction time.

|
Don't suck |
The PCB manufacturer regularly checks the wearing degree of the nozzle and replaces if it’s severe; inspects the gas path and vacuum generator; checks the corresponding solenoid valve; and passes the nozzle. |
|
Suction nozzle clogging |
It can be cleaned by means of steel needles or ultrasonic vibration; it can also be cleaned with a special nozzle cleaner. |
The prototype Pcb assembly SMT nozzle is a kind of wearing part in the parts of the placement machine. When there is a problem with the SMT nozzle, the PCB manufacturer can solve it in time, which can effectively reduce the production cost and improve the production efficiency.
