        In the field of electronic manufacturing, with the continuous advancement of technology and growth of market demand, PCB panelization technology has gradually become an important link in the production process .   So do you know what impact does PCB panelization have on SMT assembly?   1.  Why Does PCB Need to be Made by Panel? PCB panelization is to meet production needs. When some PCB boards are too small and do not meet the fixture requirements, they need to be spliced together for production. At the same time, panelization can also improve the welding efficiency of SMT patches, because they only need to go through the SMT process once to complete the welding of multiple PCB. In addition, panelization can also save cost. For example, for some special-shaped PCB board, waste can be reduced through panel production, thereby improving area utilization.     2.  Bad  C ases of  P anel ization   W ithout  S pacin...

      PCB panelization:  It is to splice several PCB together.  It is not only improves production efficiency,  saves costs, but also facilitates SMT welding in the later stage.  So what are the methods of PCB panelization?     1. V-CUT V-CUT is to put two or more PCB together, and then cut a V-shaped slot at the connection between the board and the board, which can be broken when in use. Since V-CUT can only cut straight lines, it is more suitable for rectangular PCB boards.  Secondly, V-CUT also has certain requirements on the thickness of the PCB, generally requiring a thickness of more than 1mm.   Because it is too thin, it will destroy the strength of the board itself, so the PCB with the thickness less than 1mm is not suitable for the V-CUT panelization method.       2.  Stamp Hole The stamp hole are some small holes drilled at the connection of the board to form a connection, and the burrs need to be remov...

       Generally, before PCB design or production,   a PCB  panelization   operation will be carried out , and after the processing is completed, it needs to be cut into   single board . So why do it?         The track of the SMT placement machine has a maximum and minimum size limit. When using 1 pcs smaller size PCB for processing, although it can sometimes pass the track of the placement machine, it wastes the capacity of the placement machine and the production efficiency is not high. However, if there are 10pcs, 20pcs, etc. single PCB in the panel, th is will not only improve the welding efficiency of the patch, but also only need to pass the placement machine once to complete the welding of multiple PCB.     After the PCB processing is complete, a lot of testing needs to be done.  Such as burn-in test, programming test, ICT test, signal test, etc.   Then it has more circulation time in the production w...
