What is a solder paste stencil?

A stencil is a thin plate with openings matching the solder pads on your PCB. Place it on the board, spread solder paste with a squeegee, then position your SMD components before reflow. The result: precise and uniform paste deposits, much faster than using a syringe.

How much does a 3D-printed PCB stencil cost?

With Stenchill, generating your stencil file is completely free. You only need PLA or PETG filament and a 3D printer. A professional stencil costs $15-30 per side, while a 3D-printed one costs just a few cents of filament.

What 3D printer settings should I use for a solder paste stencil?

Use 0.1mm layer height, 100% infill, PLA or PETG material, and a 0.2mm nozzle for best results (0.4mm nozzle is acceptable). The stencil thickness should be 0.3-0.4mm (3-4 layers).

Which EDA tools are compatible with Stenchill?

Stenchill works with Gerber files from KiCad, Eagle, Altium Designer, and any other tool that exports standard Gerber files.

Are my Gerber files stored on the server?

When a generation succeeds, your Gerber file is processed and discarded immediately. When a generation fails, only the Paste and Edge Cuts layers are kept temporarily so the bug can be investigated and fixed; copper layers, silkscreen, drill files, BOM and schematics are never stored. In individual file mode, only the Paste and Edge Cuts layers are uploaded in the first place; your other layers stay on your machine.

Barbatronic 使用 Stenchill

Barbatronic 是一位专注于机器人制作的法国创客和内容创作者。自 2019 年起活跃于 Twitch，他在 YouTube 上发布硬件教程，运营着一个活跃的 Discord 社区，并且是每年参加法国机器人锦标赛的 Les Karibous 团队的一员。在他周围，每周都汇聚着一群好奇的黑客和实践派创客，跟随他获取务实的硬件心得。

事实上，Stenchill 正是诞生于他的一次直播。在直播间的聊天讨论中，我意识到这个想法值得实现，而我也具备将其付诸实践的技能。

在本视频中，他将 Stenchill 整合到自己的制造流程中，并分享初次使用的感受。
