Double row, disposable carrier strips on request. 0" border on the board for handling it during processing. 4 Layer Stackup. It's 4-layer,1. If you want to inspect the soldermask thickness, you can take some slices of printed circuit board to measure the solder resist thickness at different locations on the circuit. A machine is needed to depanel it, as the remaining 1/3 of the board thickness left intact is surprisingly strong, and breaking it off by hand would put severe stress on the PCB. 2 or PCB trace based USB A connectors, etc, require the PCB to be the right thickness to fit in the mating portion of the connector \$\begingroup\$ Probably worth noting that 1. Stencil Thickness: Stencil or "foil" thickness is an important part of stencil design. 062", 0. but 0. 8mm, the maximum dimension is 200x300mm. It is important that: We recommend that solder mask apertures should be approximately 150µm overall (75µm per side) larger than the pads, to prevent solder mask encroachment, and that a note should be added to the fabrication drawing stating that solder mask encroachment is not permitted on the component pins/pads, How to Select FR4 Thickness. 0mm, 2.
