Building Your Own Circuit Boards, PCBs 03.07.06
Build your own Printed Circuit Boards
- perf boards
- wire wrap : to create connections but pins have to be longe
- battery: mAmps / hour
Printed Circuited Boards
- express PCB: 2-3 days
- soldering padding on holes, so do not have to apply extra solder
- thicker line on a pcb = more current
- can drill extra holes to give yourself more options
Eagle software
- gerber file, simply a bitmap form to print pcbs
- voltage, ground (supply)
- pin head libraries for headers, jumpers etc
- netline to make real connections
- use "eye" tool to check if right connections are made
- name the nets- double click to end net
- wire: only in drawing, not a real connection between components
- route tool: to make connections, links and angles onto each component
-
Manufacturers
4pcb : student pricing
gold phoenix pcb, china : cheapest but don't look through, quite slow
batch pcb: average pricing, late
- put SMD baords into toaster oven to allow solder to sink into place
