One less popular but easy-to-handle method of populating your AME structure is using conductive glue.

Step-by-Step Guide How to Use Conductive Glue

Equipment

Silver nanoparticles-based conductive glue such as H20E paste
High temper oven
Manual dispenser
Tweezers
Rubber eraser/fiberglass pen

Step 1: Cleaning the Pads

In order to clean the pads and remove oxidized silver use a simple rubber eraser. Since the silver pads of the AMEs manufactured on the NNDM DragonFly IV printer might be very sensitive, it is important to proceed with caution. As an alternative to the rubber eraser, a fiberglass pen might be used.

Step 2: Dispense Conductive Glue Paste on Pads

Depending on the size of the pads and the viscosity of the conductive paste, either a manual dispenser can be used, or the material can be applied with a small needle.

Step 3: Manually Pick & Place Components

After the conductive paste is applied, the next step is to place the components. In case of the J.A.M.E.S Coin, this will be two capacitors, two diodes, one LED and of course the NFC chip.

Step 4: Put AME in Oven and Start Curing Sequence

To cure the conductive glue, place the populated samples into an oven for about 2-4 hours at 100°C. We use a small tempering oven from Nabertherm to provide a proper drying.
