Using a router could require additional cleaning prior to shipment.Depanelization – disadvantages of some depanelization methods:.Panelization presents a number of challenges in several areas: Laser – Low mechanical stress and precise tolerances, but has higher initial capital outlay.Saw – Can perform at high feed rates, cutting both V-grooved and non-V-grooved PCBs.Can cut arcs and turn at sharp angles, but capacity is lower. Depaneling Router – Single boards are connected using tabs the router bit mills out the tabs.Higher capacity, but higher maintenance and cost. Punching – A two-part fixture punches out single PCBs.Best for cutting very large panels into smaller ones, this method is inexpensive and low-maintenance. Breaking by Hand – Only appropriate for strain-resistant circuits.Several different methods are used to depanel PCB arrays: 2) Depanelizationĭepanelization is simply removing individual PCBs from the array. This reduces surface stress and avoids splintering. Space is left between the perforated tabs and the traces and surface mounted parts. Tab-Route Panelization This method permits placing PCBs of the same or different designs together. V-Groove panelization is used where there are no overhanging components. The remaining board is quite sturdy and is depaneled by machine to avoid stress on the PCB. V-Groove Panelization – This method involves cutting 1/3 the thickness of the board from both the top and bottom with a 30- to 45-degree circular cutting blade. The two most common methods of panelization are V-groove panelization and breakaway tab, or tab-route panelization. The process allows PCB manufacturers to maintain high quality while reducing costs. Panelization, also known as an array format, is used to process multiple boards while keeping them together in a single substrate. Panelization must be done properly so that PCBs will not be broken or otherwise damaged during separation.įollowing is a discussion of PCB panelization methods, as well as some challenges that may be encountered. In addition, panelization allows PCB manufacturers to assemble multiple boards simultaneously, reducing costs and production time. Panelizing PCBs is a way to safeguard their integrity.

If the distance between the solder mask and the large copper skin is not enough, you can copy the enlarged solder mask (to meet the process capability) Go to an empty layer, delete the solder mask corresponding to the large copper skin, and enlarge the remaining solder mask as the second layer.Printed circuit boards (PCBs) need to be kept secure during the manufacturing, shipping, and assembly processes to avoid damaging the unit. The layering method is: first layer (plus layer), second layer (minus layer), third layer (plus In general, in order to reduce the amount of data, we can leave the first layer only with a large copper skin. First copy all the PADs of the circuit layer (this layer is the first layer) to an empty layer, delete the PAD corresponding to the large copper skin, and enlarge the remaining PADs to reduce the circuit layer (the second layer) ), And then copy the first layer to an empty layer, and delete the large copper skin as the third class. When the data is covered by a large area of copper foil, the distance between the line or PAD and the copper skin is not within the production requirements, and the appearance size is large, (such as the wide one), the following methods can be used to quickly repair the line or PAD and copper The distance between the skins. All this These settings will be saved in the *. Of course, click a Layer Sets and press Delete to delete the setting, or you can select each of the groups Layer. If you want to edit a layer combination, just click the AdD button and repeat the previous operation. Click the 2 button to add another layer, repeat this process until all The desired layers are added. After OK, the layer will be displayed in the box to the right of the 1 button. If you click the 1 button, a selection box of "Layer List" will pop up. Next click the number buttons on the right to add each Layer The layers contained in Sets. Hot Key 1", the surface hotkey 1 has already been used. Hot Key 1" is displayed in the "Layer Sets" list, but if it has been set in the other three types (Layer Stackup / BlinDanDBuried / MCM Technology), It will automatically start with the next unused hotkey. The name can be the default or can be defined by yourself, but the name is not Spaces are allowed. The name is entered in the "name" box on the right. In the "Layer Sets" list on the left is the name of the layer setting and its assigned hotkey number.
