Plasma treatment prior to wire bonding efficiently removes organic contaminants and thin oxide layers under high throughput conditions, quickly, efficiently and reproducibly, greatly enhancing yield and reducing bond failures.
In many electronics application areas there is a stringent requirement for ultra-clean bond pads prior to wire bonding. This is especially true in e.g. semiconductor and space satellite instrumentation fabrication. Wire bond pad contamination results in poor bond pull strength and also bond strength uniformity. Plasma cleaning may be applied as an in-line solution e.g. prior to encapsulation, or as a batch processing step with bespoke frame loading arrangements.
Plasma Treatment for Wire Bonding
- Plasma Cleaning of PCB’s prior to bonding
- Plasma Activation of printed circuit boards prior to potting & encapsulation
- Etching & desmearing of epoxy, flex-rigid and teflon printed circuit boards
- De-oxidation of gold contacts
Lead Frame Loading
Standard and custom lead frame loading arrangements are also available in all plasma cleaning system models.
