MicroFlip

A quick guide to safely use your MicroFlip !

Assembly

Step 3 of 4

In this step, we'll solder the MicroFlip PCB to your N20 motor and prepare it for wiring.

Inspect your N20 motor leads. Ensure they are clean and free of debris or oxidation.
If necessary, lightly tin the motor leads with a small amount of solder to improve adhesion.
Identify the positive (+) and negative (−) terminals on your motor.

Position the PCB: Align the MicroFlip PCB with the motor leads. The solder pads on the PCB should line up with the motor terminals.
Secure the motor: Use a helping hands tool or tape to hold the motor steady while soldering.
Heat the joint: Place your soldering iron tip so it touches both the PCB pad and the motor lead simultaneously.
Apply solder: Feed a small amount of solder into the joint. The solder should flow smoothly onto both surfaces.
Repeat for the second lead: Solder the remaining motor lead to its corresponding pad.
Inspect your work: Check that both joints are shiny and have good solder coverage. There should be no cold joints (dull, grainy appearance) or solder bridges between pads.

After soldering, verify the following:

Mechanical stability: Gently wiggle the PCB to ensure the solder joints are secure. Do not apply excessive force.
Continuity: If you have a multimeter, check for electrical continuity between the motor leads and the PCB pads.
No shorts: Confirm there are no solder bridges or stray solder connecting unintended pads.

Below you can find what an optimal microflip assembly should look like:

Problem	Cause	Solution
Cold or dull joint	Insufficient heat	Reheat the joint and add fresh solder
Solder won't stick	Oxidized surfaces	Clean the pad/lead and apply flux
PCB moves or wobbles	Weak joint	Reflow the solder connection
Motor doesn't spin	Open connection	Check continuity and re-solder if needed

With the MicroFlip PCB soldered to your motor, we'll move on to preparing the wiring and JST-PH connectors.
