Flexible Circuit Assembly has been going strong for over 30 years. SMT Polyester Assembly has used in high end assemblies for decades. In the mid 80’s I remember sitting in the room full of Motorola Engineers and talking about Satellites, the possibility of the MicroTAC cell phone replacing the Pager. Yes, Statements like this would obsolete the home phone, and everybody would carry one someday. I agree, it seemed a little far fetched at the time.
Flexible Circuit Assembly was popular in the mid 80’s with wave soldering for interconnecting, but going from SMT Kapton “Polyimide” to clear Polyester circuit to get the keypad to light seemed like an engineering challenge. Low melting point Mylar® , and high melting point 63/37 solder in high volume. SMT Polyester came to life.
The Flexible Circuit Assembly shown is 30 years old. It is the Flexible Circuit used in the Motorola MicroTAC released April 25th, 1989 and the Motorla StarTAC released on January 3, 1996,. The flex circuit shows no signs of aging. Manufactured on clear DuPont Mylar® “Polyester.” The flexible circuit assembly was constructed with gold plated keypad, tin/lead plating on the Zero Insertion Force (Zif) interconnect, Mylar®, Coverlay, 63/37 solder, and cleaned with Freon 113.
The success of the cell phone has changed the world. References: PC World reported the StarTAC at #6 in The 50 Greatest Gadgets of the Past 50 Years and sold more that 60 million StarTAC phones. Flexible Circuit Assembly with Automated Assembly Corporation SMT Flex assembly.
In Conclusion, Flexible Circuit Assembly is over 30 years strong. SMT Polyimide, and now SMT Polyester have passed the test of time. Both technologies responding as if they were manufactured yesterday. Making the electronics world lighter, more flexible, and now more reliable over time. Many new industries are adopting flex circuits such as LED Light Strips for thermal management, RFID Windshield Sticker Tags for Long Life, ABS Breaks for Thermal Shock, Aviation Air Bags for reliability, flexible heaters for conformability, medical flex for size. Many industries requiring high reliability have SMT Flex assemblies in service for over 2 decades.
