Macros Sprint Layout 60 May 2026

Sometimes a macro is 90% correct (e.g., wrong pad size or pin spacing).

| Mistake | Symptom | Fix | |---------|---------|-----| | Wrong pad diameter | Component leads don't fit | Explode macro → edit pad hole size | | Missing silkscreen outline | No outline after board fab | Add lines on layer K2 around component | | Macro placed on wrong side | Component on bottom but should be top | Right-click → To other side | | Pads too close for routing | DRC error | Explode → move pads slightly → recreate macro | macros sprint layout 60

| Macro Category | Common Examples | When to Use | |----------------|----------------|--------------| | SMD | 0805, 1206, SOT-23, SOP-8 | Resistors, caps, small transistors, op-amps | | THT | AXIAL-0.4, CAP-5mm, TO-220 | Through-hole resistors, electrolytic caps, voltage regulators | | Connectors | SIL-1x2 to SIL-1x40, Screw-TB | Pin headers, screw terminal blocks | | IC | DIP-8, DIP-16, SOIC-8 | Microcontrollers, op-amps, logic ICs | | Crystals | HC-49S, HC-49U, XTAL-SMD | Quartz crystals and resonators | Sometimes a macro is 90% correct (e

| Mistake | Consequence | Fix | |---------|-------------|-----| | Forgetting to include all pads | Missing connections in PCB | Double-check before exporting | | Using absolute coordinates | Macro inserts far away from cursor | Create it near (0,0) | | Not saving grid settings | Misaligned components | Set grid before designing macro | | Mixing layers incorrectly | Shorts or missing traces | Stick to copper (Layer 16/18) and silk (21/23) | SOP-8 | Resistors
