Usage
Hot-air rework stations can be very handy. As mentioned above, they are a crucial tool when it comes to
reworking a board. The term rework just means you are refinishing or repairing an already reflowed board,
and it is a term commonly used in the electronics world. Just think of it as doing any work to the board
that wasn't involved in the actual production process. Here are some common rework scenarios:
Polarized Components - Parts that have been placed incorrectly (backwards, shifted x degrees off). These
include ICs, diodes, some capacitors, connectors, etc.
Tombstone Parts - This is when a part (usually a resistor or capacitor) reflows only on one side. The part
usually sticks strait up resembling a tombstone.
Cold Joints - This is similar to a tombstone except the parts might not be sticking strait up, making it
harder to see the connection that is not being made.
Removing Defective Parts - Sometimes, during the IC manufacturing process, errors can arise and go
unnoticed. These ICs are then placed on perfectly good PCBs. Hot-air is great for replacing these bad parts.
Missing Components - The smaller the component, the easier it is for it to disappear. This can happen
before or during reflow, resulting in a spot where something should be, but isn't. Hot-airing a new part in
