  1. ECE 2799 Electrical and Computer Engineering Design “Prototyping Techniques” Prof. Bitar

  2. Prototyping Techniques • Solderless Breadboards w/ Jumper Wires (Temporary) • Non-Copper Clad “Perf-Boards” w/ Pins and Point-to-Point Wiring, Soldering and/or Wire-Wrapping • Prototyping Boards (w/ Copper Patterns) Point-to-Point Wiring, Soldering and/or Wire-Wrapping • Custom Printed Circuit Boards w/ Copper Traces, Copper Pads and Soldering

  3. Solderless Breadboardsby3M, RSR Electronics, & Global Specialties

  4. Pro’s Convenient Quick Easy to Change Con’s Not Very Permanent Contact Wear Out IMAX≈ 100-200mA fMAX ≈ 1-10MHz Through-Hole Components Only* * May Use “Surfboards” for SMT Devices Solderless Breadboards

  5. Good Technique Components laid out in a logical fashion Leads cut to avoid short circuits Jumpers run either horizontally or vertically Correct length wire used On-board bypass capacitors across power connections and ground Bad Technique Components laid out haphazardly Component leads overstressed Leads not cut, risking short circuits Leads cut too short, not making board contact Random length jumpers used Bypass capacitors missing Solderless Breadboards

  6. Your boards look like this, RIGHT ?

  7. NON-Copper Clad PERF-orated BoardsVector Electronics, Twin Industries, and Keystone Electronics • FR4 Glass Epoxy Phenolic • Typical Specifications (in) • 0.062 Board Thickness • 0.042 Hole Diameter • 0.1 x 0.1 Hole Pattern • Various Sizes • $0.25 / in2 (based on 10”x10” size board)* * Increases considerably for copper patterned boards.
