Chip wire bonding with open lids
WebWire bonding is the main method of making interconnections between a semiconductor die and a package or substrate. Alter Technology (formerly Optocap), works closely with our customers at the package design stage to ensure that design for manufacturing techniques are applied and wire bond design rules, where possible, are adhered to. This co ... WebRDL technology allows a die designed for wire bonding (with bond pads arranged along the periphery) to be converted into a WLCSP. In contrast to a direct bump, this type of WLCSP uses two polyi - mide layers. The first polyimide layer is deposited over the die, keeping the bond pads open. An RDL layer is deposited to convert
