Micron Laser Technology offers PCB Depanelizer and part excising services 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 combination of both.
Depending on the material and also the part requirements, MLT supplies a tool-less part removal process as final depaneling, hold-in tabs, scoring (v-grooves), and perforations. These laser processes have the advantage of speed, positional accuracy, no tooling cost or wear, no part induced stresses, and no cutting oils or any other contaminants.
Hold-in tabs are small uncut sections concerning the part utilized to secure the part in the panel. The hold-in tabs are used for easy of handling small parts or part securement for further processing. The hold-in tab width is chosen based on the amount of force desired to removed the part from the panel/sheet or known forces to get applied by downstream processes like component loading or electro-polish. MLT can make tabs in many any material and to any width and location regarding the part.
Laser scoring generates a limited depth ablation line inside the part or material set. The depth is normally 50% in the material thickness but could be controlled to your desired depth. The scoring acts similar to the hold-tab to secure the part within the panel or sheet, but provides for individual parts to get ‘snapped’ out. Laser scoring lines may also be used as being 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 another choice for tool-less part removal from a panel or sheet. Perforations could be laser formed to any size and spacing to satisfy the desired removal and Manual 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. Using a laser to do the depaneling affords the user the main benefit of speed and positional accuracy. Unlike mechanical methods there is no part induced stresses, no tooling cost and no cutting oils or other contaminants.
Laser depaneling is great for rigid-flex boards as it provides a precise approach to cut through a number of materials including although not restricted to these most frequent materials seen:
Combinations thereof, appropriate for thicknesses of rigid flex laser depanelization, rigid flex depanelizedIn addition BEST could be that provider of laser depanelization once you have lots of IoT devices which lmuteg to be precisely machined or eliminate to fit perfectly directly into small mechanical enclosures.
Due to the contact-free processing that continues with laser depanelization of printed circuit boards, there is little distortion even when thin materials are employed. When boards are milled or punched out using a mechanical tool there could turn out to be a loss precision and potentially a distortion within the outside board dimensions. Even worse it might crack solder joints when utilizing these mechanical means. In BEST laser depanelization system feature fiducial registration and internet based scaling, meaning already existing distortions could be compensated and also the cut contours positioned precisely in the layout.
The techniques for straight line Laser Depaneling, that are setup for rectangular-shaped PCBs, all cut or crush the advantage in the board edge. These methods include die cutting, punching or V-scoring the assembly or using a wheel cutter or a saw. The sawing method typically uses a single rotating blade spinning at high RPM to cut the panel in to the shapes required. This technique produces heat in the eliminate area as
well as creating debris being a byproduct in the cutting operation. In V-scoring the depth from the thickness from the board is 30-40% in the original board thickness since it is cut from each side from the board. After assembly the board is broken at this particular v-score line. Alternately a “pizza cutter” cuts through the V-score of the panel and cuts the other web until the boards have been in their final cutout shape thereby putting strain on the components and solder joints-especially those nearby the board edge. In another method, the singulated board outline could be punched out make up the panel. This requires that a new punch be utilized for every single kind of circuit board which means it is really not a flexible type of method of board reduce. The punch force may also bend or deform the sides of the PCB.
