Consigned Material Sourcing and Counterfeit Escape Risk Controls
Consigned material sourcing requires strict incoming package checks, chemical decapsulation, and clear contract risk allocation to prevent counterfeit escapes.
Carrier Tape
Packaging Method
An embossed plastic ribbon with formed pockets holds surface mount devices during automated component placement. Automated feeders pull the carrier tape through assembly machines to present each component to a vacuum nozzle. The component remains secure in its pocket until the cover tape peel occurs.
Dimensional Control
Precise physical spacing ensures that pick-and-place equipment locates each electronic part without misalignment. Standard pocket widths and feed hole pitches prevent feeding jams on the assembly line. Pockets must match the height and width of the specific integrated circuit to stop components from flipping or rotating during transport.
A loose fit often results in pick errors or component damage. Optical sensors in the assembly head verify the pocket position using the round sprocket holes punched along the tape margin. This secondary check stops the machine if the tape drifts.
Standard Alignment
Industry specifications define the standard tape widths ranging from eight millimeters to over seventy-two millimeters to accommodate various package sizes. This standardization permits assembly plants to use uniform feeder modules across different manufacturing runs. Static dissipative materials are required in the tape composition to prevent triboelectric charge accumulation.
These electrical properties protect sensitive silicon dies from catastrophic voltage spikes during de-reeling.
