Workflow

Design to Test in ~30 Minutes

PCB design loaded in the PewCB software
Blank positioned in the PewCB work tray
Laser-cut solder paste stencil
Reflow soldering of the assembled prototype board
Completed electronics prototype ready for testing
Prepare Your Project
Design your PCB, export Gerbers, open them in the PewCB app, and press Start.
Laser Processing
The laser selectively removes solder mask, copper and substrate, leaving behind traces and pads.
Stencil Fabrication
Attach the tin stencil sheet to the finished PCB, and the laser will cut the openings perfectly aligned with the pads.
Assembly & Soldering
Apply solder paste, place the components, reflow on a hot plate, then brush with IPA to clean off residue.
And its done!
Your prototype board is complete and ready for testing!

Malleable Stencils

A new approach to prototype assembly: once the PCB is fabricated, attach a single-use stencil sheet to the board and place it back on the tray platform. The laser automatically cuts the stencil openings according to the Gerber Paste layer. Once the solder paste is applied, the stencil is discarded.
This approach makes paste application fast and precise — accelerating PCB assembly.

Perfect Pad Alignment

The stencil keeps firmly attached to the board during and after processing. This ensures precise pad alignment without manual fiducial matching, or additional fixturing mechanisms.

Fast Paste Application

The stencil remains securely attached to the PCB during solder paste application. This allows engineers to apply paste quickly and cleanly without a stencil frame, clamps, or external alignment jig.

Tin Plating of Pads

As the stencil openings are cut, a thin protective tin layer is deposited onto the copper pads, improving solderability during assembly.
