Visual Guide to socket a Microcontroller

Required Hardware

• Elite-C or Pro Micro C
• Mill-Max 315-43-112-41-003000 low sockets for Elite-C
• Machined header sockets Pro Micro C
• Mill-Max connector pins
• Soldering iron and solder
• Flush cutters and needle-nose pliers
• Kapton or regular tape

Step 1: Solder Sockets onto PCB

Cut sockets with a flush cutter into rows of 12 (if they are not pre-cut). Tape and solder them on the correct MCU pin columns.

Step 2: Cover Sockets with tape

Cover both sockets with tape to protect solder flow from fusing with sockets. Heat-resistant Kapton tape is preferred but any regular ones will work as well.

Step 3: Insert Mill-Max pins

Use needle-nose pliers to hold and pierce connector pins into the sockets. Mill-Max pins will “click” into the 315-43-112-41-003000 low profile sockets. Make sure all pins are all fully inserted and even:

Step 4: Solder the MCU

(Double (and triple) check for microcontroller pin orientation before proceeding. Do not rely on face up or down assumption). Place controller over the pins and tape it down flat. Correctly inserted pins will only protrude a bit out the controller holes. Solder each pin carefully:

Step 5: Remove MCU and tape

Pry the MCU carefully and evenly from the socket, and remove the protection tape:

Done.
