minimum-trace-clearance-pcb
The minimum PCB trace and pad clearance. The smallest clearance between trace to trace or Pads to Pads) are 1.6mil(40um) to 3mil(76um). we offer 40um Pads clearance PCB, 50um(2mil) gap PCB, 60 um gap PCB. and 70um spacing PC Boards. We are the Minimum trace clearance PCB manufacturer.
In the Standard design: the PCB trace spacing and Pad clearance will be about 4mil(0.1mm) to 6mil(0.15mm). maybe 8mil to 10mil spacing. that will be easy to produce. But in some especial PCB design. the trace and pads clearance will be getting smaller and smaller. you have to design the spacing more and more smaller. Save the space and Improve product efficiency. So. we can produce the smallest trace and Pad clearance PCB boards. and The qualities of our PCB are very stable. Before we send out the boards to you. All of them will be passed the Elec Testing.
the Best smallest trace and Pad clearance PC board: The Line to line spacing are 1.6mil. the minimum pad clearance/the smallest gap are 1.6mil too. Most of our customer have used 50um(2mil)trace clearance( pad gap) or 60um trace clearance( pad gap) PCB products. the finished PCB clearance tolerance are +/-10um. about the PCB thickness. For 2 layer PCB. we can finish the PCB thickness with 0.1mm(4mil). 0.15mm, 0.2mm, 0.3 mm to 2.0mm. For standard multilayer PCB or HDI multilayer PCB boards. we will finish the board thickness from 0.3mm to 5.2mm.
The minimum Via hole is 4mil(0.1mm). the via holes will be drill with the laser ways. we suggest you to design the via size more bigger. 0.25mm to 0.4mm will be good. the big via holes cost will be more cheaper than 4mil(0.1mm) laser drilling.
The PCB NO MOQ request. One time. you can order 1 pcs to 10 pcs. 10 pcs to 100pcs. or 100 pcs to 10000pcs. some times. the 1 pcs price and 10 pcs price are same.
