Modle: JL-AM2 Structure: Precision Ball Screw /Motor Length of the arm: 700mm Control system: PLC Position: X/Y/Z direction adjustable Characteristics: Don¡¯t need to install, just put it in the side of testing machine and then connect to the power and signal line. It can receive the¡°pass¡± signal of the testing machine, marked by itself, and distinguish the good and fail boards completely. Also if there are some problems existed in process, it can trace back to the question point immediately. Conveyed by motor, the speed is very fast. It can finish the mark in the move upward process of plate, without influencing the testing efficiency. Adopt mechanical arm consists of Precision Ball Screw, can fix an accurate position, get clear marks and more stable. Use dry printing ink, it will be freezed very soon. This machine can prevent leak testing, and monitor itself at any time, improve the quality of PCB boards.
