Exterior reassembly

The inside looks good, so it's time to close up that device you've been repairing. Most electronics nowadays have snaps that help hold the parts of a case together. By checking the style of the snaps, you can tell how they
fit together. Line up the snaps on the case as carefully as you can. Then put pressure on them. Ideally, they'll pop into place and the edges of the case will fit together tightly. If you see a noticeable bulge, recheck
your snaps. One might not be securely fastened. Keep in mind that snaps are known for being weak. Sometimes one or two broken snaps are no big deal.
However, sometimes broken snaps can make a case wobbly. You can use a plastic melting iron to mend the snaps, but they won't be as sturdy as before. Screws often also hold a case together. Be careful when reinstalling screws or else you can damage them. Plastic cases can also be cracked by installing screws incorrectly. A stripped screw is very hard to remove later on when you need to open the case again. Insert the screws into the case, but don't tighten them yet. Make sure all the screws are in the right place and that you don't need to open the case again. Grip the screwdriver with your fingers and just turn the screws until they stop. You want them to be snug, but don't twist them in until they won't move anymore. Now you're ready to test out your repaired electronic device.
