Method of jet plating
WebPlating Common lead-frame materials are copper alloys (usually with a small percentage of iron) and ‘Alloy 42’, which is an alloy of iron (58% and nickel (42%). These materials have a close TCE match with silicon and good strength and workability. Bondability is generally enhanced by spot plating with silver. Web22 jun. 2024 · Abrasive Water Jet Cutting Abrasive Water Jet Cold Cutting is another method of cutting on-site structures without using a flame or heat. This makes the process well suited to environments where there is a risk of fire or explosion. This method uses an incredibly high-water pressure delivered through a small orifice at around 60,000 PSI …
