Number 1: PCB Panel use pcb panel usage

Figure 2 reveals the family member expense payments in the production of printed motherboard for a conventional printed motherboard (100 * 160mm, 8 openings per cm2, 127µm track width/distance, surface area: HAL) depending upon the variety of layers. Essentially, only the costs for boring, cutting (racking up or milling), the electrical examination, packaging as well as for some material elements are straight depending on the number of printed circuit boards that can be suited on a panel. The continuing to be expense elements are independent of the number of printed motherboard per panel.

Figure 2: Expense elements in the production of printed circuit card pcb parts

Normally speaking, it can be stated that approx. 70% to 80% of the PCB production costs are to be regarded as dealt with expenses, i.e. they are independent of the number of PCBs per panel. For the arrangements displayed in Number 1, this implies that the 8 circuit card (Panel B) can be made and also bought practically at the overall price of 6 circuit card (Panel A). The ideal advantage dimension in terms of producing prices is certainly dependent on the manufacturer. However, thinking about the commercially readily available panel cuts of 610 * 530mm or 1070 * 1225mm (typical sheet format) and the mounting margins and spacing needed for the manufacturing process, the PCB panel application and thus the price development in the PCB manufacturing for numerous PCB suppliers is an optimum advantage size of approx. 245 * 285mm.

The setting up process has cost components that are straight related to the number of parts per benefit as well as thus to the variety of printed motherboard per benefit, such as: Intake of solder, direct SMD or THD setting up prices per element as well as AOI cost per part. The expenses for packaging the circuit boards, an electric function test and for dividing the circuit card from the panel are symmetrical to the number of circuit boards in the panel. Other price elements are nearly independent of the number of printed motherboard in operation or the variety of parts on the published circuit card:

Throughput time of the benefit in the soldering system, Time for paste printing, The placement maker is idle throughout retraction/extension or adjustment of use. Assembly prices for PCBs advantage

This decreases the processing costs in the PCB setting up for a benefit with an enhancing number of PCBs in the benefit, as displayed in concept in Figure 3. The following briefly analyzes whether taking full advantage of the number of published circuit card in terms of use is constantly highly sensible.
