[labnetwork] UV light bulbs for mask aligner

[Howard Northfield]

Absolutely love the idea of LED for many reasons.

Looked into it .... To upgrade my OAI 200-IR to LED is many, many thousands of $$USD.

Something to consider is possibly a UV-LED upgrade for less total cost of ownership over time and the removal of lamp sourcing issues. I do not know the US situation so well but for UK-EU there are a couple of independent vendors I am aware of who may be able to assist:

It is something I am lightly looking into, I recall the last quote was approximately £8k per EVG aligner but like all things that was years ago and has probably gone up since

Hi all,

After 6 months of waiting for Atlanta light bulbs (both 350W and 1000W) we are forced to look for alternative vendors.

If you have any recommended vendors with a reasonable lead time on UV bulbs for mask aligners please share your secret.

Thanks,

Nava
