Not high when 2) integrated circuit board mounts to SMD chip mounter utilance, not high during plug-in unit to plug-in unit production line utilance yet.
3) connecting line is more when final assembly, causes complete machine production efficiency to descend.
Consider that from the manufacturing cost aspect there is following shortcoming in the design that adopts two discrete two-sided pcb boards to be connected with two machine hardware simplicity:
1) cause the production cycle long, the not high cost of entire product that allows of production line utilance improves greatly, to the very inconvenience of realization of the economic benefit of product.
2) connecting line and splicing ear are more, have improved the cost of product.
3) area of the design of two boards increase pcb board has increased the cost of pcb board and complete machine.
Consider that from optimizing performance and expanded function there is following shortcoming in the design that adopts two discrete two-sided pcb boards to be connected with two machine hardware simplicity:
1) connecting line is more, and the performance index of product have been produced certain influence, has reduced the technical indicator of product.
Failure rate when 2) having increased production especially aspect complete machine production, is brought very big inconvenience to the control of production efficiency and production cost.
3) design that adopts two machine hardware simplicity to connect, user's line complexity needs two remote controllers simultaneously, operates also comparatively loaded down with trivial details.
In sum, adopt two designs that discrete two-sided pcb board is connected with two machine hardware simplicity, have design and complex manufacturing, manufacturing cost height, and the few shortcoming of extendable functions.
