Process Format
Transfer of electronic components from bulk containers into pocketed carrier tapes for assembly. Tape and reel repackaging allows the parts to be used by automated pick and place machines during circuit board assembly. This format protects the leads from damage and ensures a high speed of production.
Carrier Specification
Dimensions of the pockets must match the size and shape of the component exactly. In tape and reel repackaging, the carrier tape is sealed with a cover tape to keep the parts in place. The pitch between the pockets and the width of the tape are standardized to fit into the feeders of the assembly equipment.
This uniformity is necessary for the mechanical synchronization of the machine.
Static Protection
Materials used for the tape and the reel must be dissipative to prevent the buildup of electricity. Tape and reel repackaging requires the use of antistatic coatings to protect sensitive semiconductors from electrostatic discharge. If the tape generates a charge, it can destroy the internal circuitry of the device.
Verification of the surface resistivity is a standard quality check.
Handling Efficiency
Bulk parts are converted into a continuous stream that reduces the downtime for machine reloading. Tape and reel repackaging is often performed by services that specialize in high volume processing. The reels are labeled with bar codes to provide traceability for the lot number and the quantity.
This approach supports the lean manufacturing of electronic devices.
