Hi,
        I work for a company that makes stepper machines for microlithography in making flat panel displays.  We are thinking of adapting this technology to be used in making printed circuit boards (esp. for micro chip modules).  I have inquired that line resolution is much coarser in pcb's than in flat panel displays.  However I am not very privy to pcb microlithography and would appreciate any comments or suggestions that would help me to decide whether I should pursue this field of application.  I am specifically interested in the following questions: Are there any other design standards besides IPC?  What types of substrates are used and what companies produces them or laminate them?  How are these substrates registered (how do you locate their position before printing)  Any additional comments on MCM interconnects (BGA's , Wire Bond, etc) that would complicate the process.
                                        Thanks,
                                                Lou
