PCB Header Assembly Jig
Using the PCB Header Assembly Jig
Many of our Raspberry Pi expansion boards are supplied with the connectors unsoldered. We have chosen to sell the boards this way because it makes it easier for the user to modify the board by adding their connectors or fitting it in a lower profile case. To make the soldering of the connectors easier, we have designed an easy-to-use paper assembly jig which you can download and print.
Print
Download and print the PDF from the link below. Set the print size to A4 (210mm x 297mm) and set the printer not to scale to fit the page.
Cut 
Cut out the assembly jig along the solid black line. The cut-out jig should be 80mm wide by 18.5mm high.
Fold
Fold the jig along each of the broken lines. Each fold should be at a 90-degree angle.
Use
Slot the assembly jig onto the printed circuit board on the opposite side of the 40-pin connector. The jig should hold the PCB parallel when the connector is in place, making alignment and soldering easier.
