A particle getter is presented for protecting electronic circuitry from damage caused by particles or debris. An adhesive film is used to capture and retain particles, such as solder balls and wire trimmings, that pose a danger to the functioning of electronic circuitry, and thereby prevent short circuits and other malfunctions. The particle getter does not interfere with access to the circuitry, and thus may be used when conformal coating is not practicable. The particle getter is particularly useful for protecting electronic circuitry aboard a spacecraft, since particles that can cause a circuit malfunction float freely in the zero-gravity environment, where they can be captured and retained by the getter. The preferred adhesive film is space-qualified, and has outgassing properties that are within limits imposed by NASA specifications. The particle getter has applications in many places where debris is present, both in space and earthbound.
