Laser for PCB marking

The project for laser marking of printed circuit boards (PCBs) was awarded to us by a customer from Central Bohemia. This time it was necessary to solve the marking of differently sized printed circuit boards, i.e. the description of this special type of fiberglass – cuprextit.

Proposal for a solution

Laser marking device with 20W laser source of EP variant with frequency range up to 1MHz
X, Y and Z coordinate system due to large and differently thick plates
The X coordinate is provided by the linear axis with the laser bench and head, on which there is also a separate Z axis for the height adjustment of the focus
The Y-coordinate is provided by the positioning table on which the plates lie
Fixing V profile for fixing plates
Manual opening as an eco-friendly and efficient solution with safety sensor
High quality datamatrix codes and text on the cuprextit itself or engraving in the copper layer

Description of basic machine functions

Pieces or plates of printed circuit boards are laid by hand. Thus, first the worker manually opens the station door, places the PCB in the V profile of the moving table and secures the station. He selects the appropriate job on a jobbing computer with LinMark and Samlight software and the table selects the counting position according to the programmed coordinates. After pressing the process start button, the description starts by synchronizing the laser beam triggering and the table movement to the described positions. The result is then either a description on a larger platen of plates at several locations, or only one in the case of a single plate, in the form of a DMX code and a unique number. After marking, the operator manually opens the door and removes the marked piece.

Advantages of this device

Fast and precise description of the PCB
Possibility to stack different sized plates
Sufficient range of movement of the table and linear axis with head for different plate sizes
Robust station processing
Convenient electronic and visual control of the entire process
Laser marking kit quality

We can demonstrate most of the technologies we offer live or make samples.

Technician

Since 2017 we have purchased 3 laser marking stations from LINTECH. The machines have been designed to suit our type of production (piece production of steel components for mechanical seals), i.e. with an emphasis on variability and easy reconfiguration. The machines work as they should. The change in marking technology has also brought time savings in the process and comfort of work (after breaking through the initial resistance, the change was positively received by the operators).
