Hi "X",
It depends....do you mean wire bonding on chip or bonding chips on
something, e.g. a substrate? Anyway, this game seems simple, but is a
science of its own. Few good standards, few gurus like splendid bonding
professor Creswick.
First of all, I recommend that you get a good book in this disciplin. I use
the following ones, try to see if you can get any of them:
1. Chip On Board technologies for multichip modules. 500 pages with bonding
technologies.
John H. Lau / Von Nostrand Reinhold, 115 Fifth Avenue, New York, NY 10003
ISBN 0-442-01441-4
2.Hybrid Microcircuit Technology Handbook. 450 pages of processing/ James J.
Licari/ Noyes Publications, Mill Road at Grande Ave, Park Ridge, New Jersey.
3.Multichip Module Technology Handbook. 700 pages with lots of processing
parameters/ Iwon Turlik, McGraw-Hill ISBN 0-07-022894-9
4.Microelectronics Packaging Handbook. 1,100 pages covering pretty well what
you need. 50 co-writers from IBM / Rao R. Tummala, Van Nostrand Reinhold,
ISBN 0-442-20578-3
So, again, it depends on what you want to know more specifically.
