Working panel vs. shipping panel, the different size during PCB production.
«What's the main element defines PCB's size and shape?»
PCB comes in all kinds of sizes and shapes. It might be round, rectangle or irregular shape. The various PCB shape is customized for its mechanism. About the PCB size, it could be as small as nail size or as big as lighting bar in department store. Here we’re talking about per unit of PCB. However, PCB manufacturers usually deliver PCB in panel size which composes of multiple units. Have you wondered the reason behind it?
«High Usage Rate of Working panel could decrease selling price»
In most of cases, the bare PCB will be mounted after arrival. And the panel size designs for the SMT equipment. If delivering in unit size, it’s difficult for clients or PCBA suppliers to mount components by using SMT equipment because the SMT track is fixed and usually per unit of PCB will be too small to fit into the SMT track. However, if the bare PCB don’t need to be assembled by SMT equipment, sometimes the clients will ask to deliver in unit size. The panel size we called here also known as shipping panel. During PCB production, the PCB manufactures will panelize various shipping panels into one working panel for its efficiency. When the usage rate of PCB working panel is high then it could also save the production cost because fewer raw material is wasted. Which means it could help to bring down the selling price. Once it enters CNC phase, the working panel will be routed into shipping panel. And it’ll become the panel that clients received.
