Frequently Asked Questions
RapiTrim laser resistor trimming systems offer flying probes, probe cards, pogo pins or custom testing options. These can be used individually or in combination where appropriate.
Yes. For active (also called functional) trimming the RapiTrim system has the ability to interface with external instruments (standard LAN interface) through its SM200 switch matrix. Custom connections and fixtures can be provided as well.
This would depend of what needle is used and the pressure that is exerted on the probe tip, which is settable through the Z overtravel parameter. Higher pressure is needed to scrub through surface oxidation of the pad, and this will lead to higher tip wear. It is common for a BeCu tip with nominal Z overtravel to range from hundreds of thousands to millions of hits.
Fibre lasers offer extremely efficient operation (e.g. the 20W version is air-cooled) with lifetime data from the manufacturer stating up to 100k hours.
RapiTrim systems support external equipment from Keysight, Keithley and Chroma through our SM200 switch matrix. Customers can purchase and incorporate some external equipment after installaton if needed.
We believe the most useful measure of cycle time is for a complete substrate to be run on a real customer job in our application lab. If the customer wants to send us a DXF file, we can simulate this.
