At SnapEDA, we aim to provide high quality ready-to-use symbols and footprints for your electronic components. Accurate and well designed libraries for your PCBs are essential for optimal performance of your board.  A single error or the slightest offset from a badly created footprint can cause thousands of dollars in wasted prototypes, along with weeks of delays. 

Here is the round-up of the 12 tips to keep in mind while designing symbols and footprints for your PCB: 

  • Tip #1: Add a pin 1 indicator:


  • Tip #2: Keep a 0.25mm silkscreen to pad clearance:


  • Tip #3: Arrange pins based on function and electrical type:


  • Tip #4: Use standard schematic symbols:
