BEST Inc. provides laser depaneling services for printed circuit board manufacturers as well as EMS and OEMs. BEST’s numerous lasers are equipped to take care of volumes from small prototype to large production runs. Laser depaneling can cut through plastics, ceramics and metals or some combination thereof. This is the right approach to use when there are actually sharp corners or many tight radii of curvature within the PCB Router or maybe in the flex circuit.
Depending on the material along with the part requirements, BEST laser services provides a tool-less part removal process by means of final perforation, scoring and hold-in tabs. Employing a laser to do the depaneling affords the user the main advantage of speed and positional accuracy. Unlike mechanical methods there is not any part induced stresses, no tooling cost with out cutting oils or any other contaminants.

Due to the contact-free processing that continues with Laser Depaneling of printed circuit boards, there is little distortion even if thin materials are being used. When boards are milled or punched out by using a mechanical tool there might turn out to be a loss precision and potentially a distortion in the outside board dimensions. Even worse it might crack solder joints when you use these mechanical means. In BEST laser depanelization system feature fiducial registration and on-line scaling, which suggests already existing distortions may be compensated along with the cut contours positioned precisely within the layout.
Similar to scoring or v-grooves, laser perforations are another choice for singulated board removal coming from a panel or sheet. Perforations can be laser formed for any size and spacing to satisfy the required removal and securement forces.
Laser scoring can create a limited depth ablation line inside the panelized boards. Most of the time the depth in the score lines are 50% of your material thickness and can be controlled to a desired depth. The scoring acts inside a manner like the hold-tab to secure the part within the panel or sheet, but enables individual 19dexjpky to become ‘snapped’ out after processing. Laser scoring lines could also be used like a deliberate path for crack propagation or stress relief. When performing the score lines as being a service BEST either can make use of the IPC guidelines or follow customer requirements.
Hold-in tabs are small uncut sections around the board which are employed to secure the PCB Punching from the panel. The hold-in tabs can be used as simplicity of handling small boards or for printed circuit board securement for added processing. The hold-in tab width is chosen based on the level of force desired to remove the part from your panel/sheet or known forces being applied by downstream processes like component loading. BEST laser services can make tabs in the majority of board materials as well as nearly any width and site concerning the part.
