Micron Laser Technology provides PCB Depanelizer and part excising services for consumer products, original equipment manufacturers, and printed circuit board manufacturers. MLT’s numerous laser machining centers are geared up to deal with 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 also the part requirements, MLT offers a tool-less part removal process as 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, without any cutting oils or other contaminants.
Hold-in tabs are small uncut sections about the part utilized to secure the part within the panel. The hold-in tabs can be used as 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 from your panel/sheet or known forces to get applied by downstream processes like component loading or electro-polish. MLT can create tabs generally in most any material and to any width and location regarding the part.
Laser scoring produces a limited depth ablation line in the part or material set. The depth is generally 50% in the material thickness but may be controlled to a desired depth. The scoring acts similar to the hold-tab to secure the part inside the panel or sheet, but allows for individual parts to get ‘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.
Similar to scoring or v-grooves, laser perforations are another choice for tool-less part removal coming from a panel or sheet. Perforations may be laser formed to any size and spacing to fulfill the required removal and Manual PCB Depanelizer. Depending on the material and also the part requirements, BEST laser services offers a tool-less part removal process by means of final perforation, scoring and hold-in tabs. Using a laser to perform the depaneling gives the user the benefit 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 possesses a precise approach to cut through many different materials including however, not restricted to the following most typical materials seen:
Combinations thereof, ideal for thicknesses of rigid flex laser depanelization, rigid flex depanelizedIn addition BEST could be that provider of laser depanelization if you have a lot of IoT devices which lmuteg to become precisely machined or cut out to fit perfectly into small mechanical enclosures.
As a result of contact-free processing that goes on with laser depanelization of printed circuit boards, there is very little distortion even if thin materials are utilized. When boards are milled or punched out using a mechanical tool there may prove to be a loss precision and potentially a distortion within the outside board dimensions. Worse yet it might crack solder joints when you use these mechanical means. In BEST laser depanelization system feature fiducial registration and online scaling, which suggests already existing distortions could be compensated and also the cut contours positioned precisely inside the layout.
The methods for straight line PCB Laser Depaneling, that are set up for rectangular-shaped PCBs, all cut or crush the advantage from the board edge. These techniques include die cutting, punching or V-scoring the assembly or by using a wheel cutter or a saw. The sawing method typically works with a single rotating blade spinning at high RPM to cut the panel in to the shapes required. This method produces heat in the reduce area as
well as creating debris as being a byproduct from the cutting operation. In V-scoring the depth from the thickness from the board is 30-40% of the original board thickness since it is cut from each side of the board. After assembly the board is broken at this v-score line. Alternately a “pizza cutter” cuts from the V-score in the panel and cuts the remaining web till the boards will be in their final cutout shape thereby putting strain on the components and solder joints-particularly those nearby the board edge. In another method, the singulated board outline can be punched out make up the panel. This requires that the new punch be used for every form of circuit board meaning it is far from a flexible type of way of board eliminate. The punch force can also bend or deform the sides from the PCB.
