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 own 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.
Download and print the PDF from the link below. Set the print size to be A4 (210mm x 297mm) and set the printer to not scale to fit the page.

Cut out the assembly jig along the solid black line. The cutout jig should be 80mm wide by 18.5mm high.
Fold the jig along each of the broken lines. Each fold should be at a 90 degree angle.
Slot the assembly jig onto the printed circuit board on the opposite side from the 40 pin connector. The jig should hold the PCB parallel when the connector is in place making alignment and soldering easier.
