Troubleshooting

If your Eggtimer Remote Switch doesn’t work after assembly and testing, take a deep breath,

get out a beverage to clear you mind, and start troubleshooting…

Check Your Solder Joints

The very first thing you should do is to check out all of the solder joints under a lighted

magnifier, or with a 10x jeweler’s loupe or magnifier. The most common reason for things not

working are solder bridges, i.e. putting too much solder on the pads and shorting two adjacent

pads together. You can also get into problems by bridging pads with “vias” on the board, the

smaller holes that don’t have any components soldered to them. Most of the holes and the pads

are very small, so it doesn’t take much solder to get a nice “tented” solder joint. If you get a

solder bridge, heat it up and use a solder wick or a vacuum bulb to remove the excess;

afterwards, we recommend resoldering the joints. Note: NEVER use “canned air” or

compressed air to “blow away” excess solder. The resulting solder splatter will almost always

cause more damage than the original solder bridge.

Another thing to look out for is “cold” solder joints, they look dull and blobby compared to a

nice shiny “tented” solder joint. Cold solder joints won’t conduct well; at the low power that

the Remote Switch uses this could easily keep things from working. If you have a cold solder

joint, heat it up and put just a little bit of solder on it, the main idea is to get a little more flux

on the joint. If there’s too much solder, use a fine solder wick or (preferably) a vacuum bulb to

remove the excess, then heat it up and resolder the joint.

Check Your Component Polarity

Most of the components aren’t polarized, with some notable exceptions. The outline of the

parts is silk-screened on the board, so you should be able to see readily if you have a

component soldered in backwards. Some of the components are not symmetrical (i.e. the

voltage regulators) so they would be difficult to install backwards, too. Components that are

polarized AND symmetrical are:

• The processor. Whatever you do, DO NOT install this component backwards… it will be

virtually impossible to remove and you will almost certainly damage the board trying to do so.

• The LEDs, the side with the long lead should be inserted into the holes marked “+”.

Unfortunately, once you’ve soldered them in and clipped the leads it will be difficult to tell, so

make sure you get it right the first time.

If you inserted a component incorrectly, you will have to carefully unsolder it, clear any solder

residue from the holes, and resolder it. If you find that a component was soldered incorrectly,

you will have to use a vacuum bulb or vacuum desoldering tool to unsolder it. We cannot
