We are working with a customer who has above market budget available to buy back an EVG / EV GROUP 620 mask aligner by the end of Q2.
They need to replicate their existing system and buy back a 6” top and bottom side aligner with BSA and IR option included.
Their engineers have forwarded the main technical questions they need to evaluate to proceed with the purchase:
Vintage?
Missing parts list?
What is the exposure power?
