The so-called ' extrusion ' is to reduce the distance between board and board, so as to reduce the size of the whole panel, save production materials and reduce production costs On the premise of each process can be produced, as far as possible ' squeeze '. In FPC flexible PCB panel, you need to know those following principles: All panel methods must follow the principle of material saving under the premise of production. Generally, FPC flexible circuit boards have three panel methods, namely, conventional panel, oblique panel and backward panel. In the production process of FPC flexible circuit board, in order to save cost, improve production efficiency, shorten the production cycle, often use the method of panel production, rather than single chip production. Instructions and methods for panel FPC flexible circuit boards Speed and efficiency: From paste printing to component assembly, soldering, and even testing, as part of a large array, processing multiple boards at once is faster and more efficient. Product Safety: Panelization protects the PCB from shock and vibration during assembly. Mass production: If you need to build a large number of PCBs, panelization will save you time and money. ![]() In our factory, our mini edge rail is 5mm. For breakaway rails, you can also use a v-scoring or tab route to connect then you can cut the rails easily after assembly. So it is usually used in assembly PCB boards. Tab route with tab,tab width has to be at least 2mm, please find following image.īreakaway rail, also called edge rail, is a rail at the edge of panel boards to fix the panel boards on a machine more easily. ![]() Holes space has to be ≥0.35mm, usually we will add 5-6 holes to each tab, please take following image as reference. Tab route with breaking holes(stamp holes)įor tab route with breaking holes diameter should be ≥0.45mm, regular diameter is 0.55mm-0.6mm. One is tab route with breaking holes(stamp holes) and the other one is tab route with tab(no holes). There are 2 kinds of tab routes be used for panel. However, For the tab route, the space between boards should be 1.6mm.įor panel with tab routes, 1.6mm space is needed between boards. Tab route and stamp holesįor tab route and stamp holes, it can be used in the irregular boards. More information about V-scoring,please check PCB V-Scoring. Scoring lines must be straight horizontal and vertical lines are possible, so the board's frame must be regular, and the size of boards must be over 45mm*60mm.įor stability, We recommend using V-scoring only for board thicknesses greater than 0.6mm. The gap between the individual circuit boards in the layout is 0mm based on the minimum spacing between copper pattern (trace/pad/copper ground) and V-cut line is 0.4mm. We also require the v-scoring boards, please observe the following rules: V-scoring is the v-shape line to connect boards for convenience separation. V-scoring is the most popular way in the PCB panel. V-scring has to be continuous and can not be stopped in panel, if you have many different boards like following image to be panelized, we suggest add tab routes between boards instead of V-scoring. ![]() Please take following images as reference. V-scoringįor V-scoring panelization, space between boards can be 0mm or 2mm. For the routing process, it has three types: V-scoring, Tab route, and stamp holes. That means we help you connect the single boards(same or different are both OK) on one big panel by different route process, then it will be easy for you to break them into single PCB. Also, we can provide the service to help you panel the single board for free. We can make the boards according to your panel design. PCBWay, as the most professional manufacturer in this field for more than a decade. The panel can reduce the time and labor for production and testing. PCB panel is a consideration for both PCB manufacturing and PCB assembly cause some boards are irregular.
