Ever encountered problems in prototyping SMD circuits? Here's a quick solution to your problem.
What did you use the SMD chips for?
Oh that is my "High Effeciency Amplifier" prototype (8002B chip). I'm going to use that for the much awaited "DIY Supercharged Bluetooth Speaker (v2.0)" guide. It took me hours to decide whether I should skip the prototyping stage and go directly to designing the PCB Layout.
SMD chips are the key to making compact devices, but prototyping SMD based circuits could sometimes be a pain in the a$$, simply because they have a different pin distance compared to the standard DIP package (which has a 1mm gap).
Amplifier Test Using The Converted Chip:
Step 1: Parts & Materials
- Your Desired SMD Chip Model (8-pin)
- Leatherman Multitool
- 30W Soldering Iron
- Soldering Paste
- Soldering Lead
- Male Headers
- Perf Board
Step 2: Cutting the Perf Board
Simply cut a fraction of your perf board. Mine is 4x4 (hole count) since I am dealing with a 8 pin SMD chip.
Step 3: Temporary Mount
Drop a small amount of superglue, to hold the chip in place.
Step 4: Carefully Mount
Use your leatherman as a tool for for mounting the chip. Be sure to mount it in the exact center.
Step 5: Breadboard As Pin Holder
The male headers tend to wobble when soldering. Use your breadboard to hold them in place while soldering.
Step 6: Solder the Chip
Use a 30W soldering iron to prevent the SMD chip from getting damaged from heat.
Step 7: You're Done! Let's Start Prototyping!
After hours of frustration, I can now start prototyping my amplifier circuit.
