<a href="https://www.allpcb.com/online_pcb_quote.html" target="_blank">PCB cost</a> is complex to calculate,because every piece of PCB is customized by&nbsp;different customers.<br /> <br /> 1.Different difficulty<br /> <p> PCB final price will be affected by different materials and production processes.Even two boards with the same material and production, different difficulty will also&nbsp;cause different costs.<span style="line-height:1.5;">For example, two boards with holes, &nbsp;one aperture greater than 0.6mm and the&nbsp;</span><span style="line-height:1.5;">other one are less than 0.6mm will form different drilling costs.</span> </p> <p> <span style="line-height:1.5;"><br /> </span> </p> <p style="text-align:center;"> <span style="line-height:1.5;"><img src="https://file.allpcb.com/bbs/17/04/25/111544462.jpg" alt="" /><br /> </span> </p> <p> <br /> </p> 2.Different requirements<br /> <p> Different requirements will result in different prices. Frequently, there are 98% pass&nbsp;rate if according to IPC-A-600E,Class1,but may decrease to 90% if request&nbsp;according by class3,so the price for PCB produced by class3 is higher than&nbsp;class1. </p> <p> <br /> </p> <p style="text-align:center;"> <img src="https://file.allpcb.com/bbs/17/04/25/111819245.jpg" alt="" /> </p> <br />
