Micron Laser Technology offers PCB Depanelizer and part excising solutions for customer products, original equipment manufacturers, and pcb manufacturers. MLT’s numerous laser machining centers are geared up to handle volumes from prototyping to long production runs. Laser depaneling or part excising can cut through metals, plastics, dielectrics, or a mixture of both.
Depending on the material and the part requirements, MLT supplies a tool-less part removal process by means of final depaneling, hold-in tabs, scoring (v-grooves), and perforations. These laser processes have the main benefit of speed, positional accuracy, no tooling cost or wear, no part induced stresses, and no cutting oils or other contaminants.
Hold-in tabs are small uncut sections concerning the part used to secure the part in the panel. The hold-in tabs can be used for easy of handling small parts or part securement for additional processing. The hold-in tab width is chosen based on the quantity of force desired to removed the part through the panel/sheet or known forces to be applied by downstream processes like component loading or electro-polish. MLT can produce tabs in many any material and also to any width and location concerning the part.
Laser scoring generates a limited depth ablation line in the part or material set. The depth is usually 50% in the material thickness but could be controlled to some desired depth. The scoring acts like the hold-tab to secure the part in the panel or sheet, but allows for individual parts to become ‘snapped’ out. Laser scoring lines may also be used as a deliberate path for stress relief or crack propagation. Prototypes utilize scoring lines in metal to accurately bend and form parts into condition without expensive forming dies.
Much like scoring or v-grooves, laser perforations are an alternative choice for tool-less part removal coming from a panel or sheet. Perforations could be laser formed to the size and spacing to meet the required removal and Pneumatic PCB Depanelizer. Depending on the material and the part requirements, BEST laser services supplies a tool-less part removal process as final perforation, scoring and hold-in tabs. Utilizing a laser to execute the depaneling affords the user the advantage of speed and positional accuracy. Unlike mechanical methods there is not any part induced stresses, no tooling cost with no cutting oils or any other contaminants.
Laser depaneling is perfect for rigid-flex boards as it provides a precise approach to cut through a variety of materials including but not limited to these most typical materials seen:
Combinations thereof, ideal for thicknesses of rigid flex laser depanelization, rigid flex depanelizedIn addition BEST may be that provider of laser depanelization when you have a lot of IoT devices which lmuteg to get precisely machined or cut out to suit perfectly into small mechanical enclosures.
As a result of contact-free processing that goes on with laser depanelization of printed circuit boards, there is little distortion even when thin materials are utilized. When boards are milled or punched out utilizing a mechanical tool there could end up being a loss precision and potentially a distortion inside the outside board dimensions. Worse yet it may crack solder joints when using these mechanical means. In BEST laser depanelization system feature fiducial registration and web-based scaling, meaning already existing distortions could be compensated and also the cut contours positioned precisely in the layout.
The methods for straight line PCB Laser Depaneling, which are create for rectangular-shaped PCBs, all cut or crush the advantage from the board edge. These methods include die cutting, punching or V-scoring the assembly or by using a wheel cutter or perhaps a saw. The sawing method typically works with a single rotating blade spinning at high RPM to reduce the panel in to the shapes required. This technique produces heat in the cut out area as
well as creating debris as being a byproduct of the cutting operation. In V-scoring the depth from the thickness in the board is 30-40% in the original board thickness since it is cut from either side of the board. After assembly the board is broken around this v-score line. Alternately a “pizza cutter” cuts with the V-score from the panel and cuts the other web till the boards are in their final cutout shape thereby putting strain on the components and solder joints-particularly those close to the board edge. In another method, the singulated board outline may be punched out constitute the panel. This involves which a new punch be utilized for every single type of circuit board which suggests it is far from a flexible type of method of board cut out. The punch force could also bend or deform the edges of the PCB.
