arduino or pi shell PCB etch tank

thingiverse

This thing is the wet etch tank for mini PCB manufacturing like arduino or Pi SBC shell. User can modify in etch_tank_x, etch_tank_y, etch_tank_z and border_tk 4 parameters to enlarge or reduce the tank dimensions. Print Settings Printer: Creative CR-8 Rafts: No Supports: Yes Resolution: 0.1-0.15mm/layer Infill: 25% Notes: Border thickness recommend > 3 x of exit pupil. Post-Printing Water leakage test requirement before PCB etch Please check the water leakage before you start to etch your PCB. Due to layer stack seams, there might be some leak position on this tank if the 3DP in poor conditions. Arduino or Pi shell PCB etch tank with air pipe. The tiny tank can be applied for small printed circuit board.Low liquid consumption is this thing's property. How I Designed This Bubbles uniformity check in 0.22mm air hole size. This video shows the every positions have bubble. Standards NGSS CCSS Overview and Background High etch solvent waste in old PCB etcher model Old PCB etch tank need > 900 ml etch liquid. It's too waste for mini PCB makers. So I design this mini tank to reduce the etch liquid usage in < 10x10 cm PCB. Lesson Plan and Activity Just try it. Please feedback any issues. Thanks!
