Hello: Since many of my brethren have already thrown in their two cents on this topic (I think we're up over a dollar!), I thought I would share a few words about where HADCO is on mass via formation. I fully understand that we are not on the Technet to sell our companies, but there may be many of you out there who are toying with the idea of designing mass microvias. Having read the information from some of the competition, here is where HADCO is. Because of our diverse customer base of over 500, we have decided to go in multiple directions to get all of the bases covered. PLASMA ETCH: HADCO is one of (3) stateside licensees of the Dyconex process. The others are Merix, and Continental Circuits in Arizona. We plan on working together to develop design guides. Merix gave an excellent overview of this process at SMI recently. PID (Photoimageable Dielectric): HADCO has already produced boards using this process. We have worked with a few suppliers of this material. It is similar to the LPI mask systems that already exist. I am aware of one other US shop (Continental in FL.) that has gone in this direction. LASER: HADCO will soon be getting in some laser equipment for mass microvia formation (end of calendar year). Zycon has already done an adequate job of discussing this process on the Technet. IBM/SLC: HADCO is investigating purchasing the licensing agreement for this process. I am not too familiar with this process, but I believe it is similar to PID, but is dry film instead of liquid. HADCO would be happy to talk with any existing or potential customer concerning these processes and our offerings. Please contact me off-line <[log in to unmask]>, and I will make sure that the appropriate person gets in touch with you to discuss things further. Once again, I apologize if anyone thinks this is a "self-sell", but the horse was already out of the barn, and I felt obligated to inform you of where HADCO is concerning mass microvia formation. There are several possible routes you might want to follow, and I believe that HADCO has all the bases covered. Thanks for your time.
