Printed Circuit Design & Fab - February 2008 - (Page 21) FIGURE 3. Single layer routing capability with UDPo. Technic offers its newest liquid photo-imageable coverlay/solder mask for flexible circuits. TechniFlex LCL 1000F is a cost-effective alternative to conventional coverlay films and an answer to the fine pitch requirements of today’s leading edge flexible circuits. FIGURE 4. nsulated bonding wires cross over each other to achieve design objectives. required. Circuit speed improves roughly one nanosecond in a theoretical lossless substrate for each 6-inch (150 mm) reduction of dual copper path (signal plus ground) according to the speed of light formula. Typically, the pinout of one chip at a time is optimized, then cycled to the next chip until the total circuit board is optimized to the satisfaction of the board designer. Once the chip pinouts are optimized, the EDA software will output a bonding schedule (net list) for input into wire-bonding machines. The chip packages are bonded using insulated bonding wire, an important feature of this new approach, to prevent shorting inside the IC package. Once optimized, there is even the possibility of creating single layer boards as shown in FIGURE 3.

For example, EDA software tools to optimize chip pinouts must be both reliable and economical before mainstream board designers will adopt them. There are already efforts being made along these lines, with several compa- Canada • China • England • France • Germany • Hong Kong Italy • Japan • Korea • Singapore • Taiwan • Thailand • USA http://www.technic.com http://www.technic.com
