BEST Inc. provides laser depaneling services for printed circuit board manufacturers in addition to EMS and OEMs. BEST’s numerous lasers are equipped to deal with volumes from small prototype to large production runs. Laser depaneling can cut through plastics, ceramics and metals or some combination thereof. It is the right strategy to use when you can find sharp corners or many tight radii of curvature in the PCB Routing or maybe in the flex circuit.
According to the material and also the part requirements, BEST laser services supplies a tool-less part removal process in the form of final perforation, scoring and hold-in tabs. By using a laser to perform the depaneling affords the user the main benefit of speed and positional accuracy. Unlike mechanical methods there is absolutely no part induced stresses, no tooling cost with out cutting oils or some other contaminants.

Because of the contact-free processing that proceeds with PCB Laser Cutting Machine of printed circuit boards, there is very little distortion even when thin materials are being used. When boards are milled or punched out utilizing a mechanical tool there might end up being a loss precision and potentially a distortion within the outside board dimensions. Even worse it may crack solder joints when you use these mechanical means. In BEST laser depanelization system feature fiducial registration and on-line scaling, which implies already existing distortions can be compensated as well as the cut contours positioned precisely within the layout.
Similar to scoring or v-grooves, laser perforations are an alternative choice for singulated board removal coming from a panel or sheet. Perforations might be laser formed to any size and spacing to fulfill the required removal and securement forces.
Laser scoring can create a limited depth ablation line within the panelized boards. Generally speaking the depth from the score lines are 50% from the material thickness and may be controlled to your desired depth. The scoring acts inside a manner similar to the hold-tab to secure the part inside the panel or sheet, but allows for individual 19dexjpky to become ‘snapped’ out after processing. Laser scoring lines can also be used as being a deliberate path for crack propagation or stress relief. When performing the score lines like a service BEST either can utilize the IPC guidelines or follow customer requirements.
Hold-in tabs are small uncut sections round the board which are widely used to secure the PCB Punching Machine inside the panel. The hold-in tabs can be used for ease of handling small boards or perhaps for printed circuit board securement for further processing. The hold-in tab width is chosen in accordance with the quantity of force desired to eliminate the part through the panel/sheet or known forces to be applied by downstream processes like component loading. BEST laser services can cause tabs in most board materials as well as nearly any width and site regarding the part.
