A. The necessity of PCB sample makeup
First in terms of quantity, good circuit PCB electronic engineers in design, and complete the PCB Layout, to the factory before mass production for small batch trial-produce proofing (PCB), in the proofing is likely to be found in the process of the board on all sorts of problems, thus to improve. This is about to choose carefully proofing, to effectively control the cost. So 5 pieces, the number of 10 pieces, it is very common. Followed by different engineers to design the information of the PCB is different, the size of the board is also each are not identical, 5 cmx5cm, 10 cmx10cm have all sorts of size and so on! The size of the production of raw materials and processing PCB is generally 1.2 x1 (m), if only a 1.2 x1 m raw material board to produce 5 pieces of 10 cmx10cm PCB, the waste of the material is very obvious, the increased cost of supply and demand is both of us don't want to see. So, proofing PCB manufacturer to save cost and improve production efficiency, to different customers, different sizes, the same process of PCB spell together to processing production, then cut out the shipment to the customer.
B. My company's PCB template engineering process
1. The design idea of size
Puzzle size design, refers to the finished product unit size, according to the customer to provide combined with factory the processing capacity of each process equipment, refer to the size of sheet metal, designed to enable customers to board a superior quality, the lowest cost of production, the highest efficiency, the most efficient puzzle dimension of the sheet metal
2. The idea of the size design factors
Puzzle size design not only affected by the customer production unit size, our company factory processes all process equipment processing capacity constraints, and restricted by upstream suppliers sheet size. So, the factors that affect the design idea of size from many aspects, such as
Customer:
Finished product unit size, plate shape shape, appearance and processing way, way of surface treatment, layer number, complete thickness, special processing requirements, and so on.
The factory:
The main factors that influence the multilayer laminated way (), puzzle on and off, tube method, various process equipment processing capacity, processing mode shape and so on.
Supplier:
Sheet metal manufacturers offer sheet size, B size, dry mold size specifications, RCC size specifications, the size of the copper foil specifications and so on.
3. The size of our puzzle design rules (mainly about double panel)
Double panel unit spacing: general double panel element spacing of 1.5 mm to 1.6 mm, usually designed to 1.6 mm
Double panel typically puzzle plates: 4 mm to 8 mm.
Double panel best puzzle size: common sheet size: 1245 mmx1041mm, optimal cutting size 520 x415, 415 x347, 347 x311, 520 x347, 415 x311, 520 x311, etc
