Introduction: Make SMD Chips Breadboard Friendly

Picture of Make SMD Chips Breadboard Friendly
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

Picture of 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.

A common technique we use in the industry is called "turtling." It is similar to this except you glue the IC to the board upside down so that the legs stick up into the air then connect the legs to where they need to go with small wires. This is especially helpful with QFN packages that do not have legs at all.

that's cool, I'll remember that if I want to muck around with SMD devices, I've shied away from them in the past but that sounds like a great technique for dealing with them

Just a note to let you know I have added this ( a year ago ) to the instructable:

Take a look at a bunch of project involving breadboards.

Is 25w soldering iron ok?

diamondmine (author)2014-07-12

I'm wondering where you purchased your perf board?

ASCAS (author)diamondmine2014-07-12

I purchased my supply from DEECO, a local electronics store.

In step 6, do you use short pieces of wire to make the connection between the SMD package and the header pins, and solder them at both ends? Or do you bridge the gap with solder alone?

ASCAS (author)privatier2014-01-10

I just bridged the gaps with lead alone.

Using a breadboard to hold pins is neat, but you might need to be quick to avoid the heat melting the plastic of the breadboard.

That's pretty smart!
you'r 'ables are awesome! great job man!

Hehehe, thanks! :)

what smd chip are you using?
