LID SEAL PREFORMS

 

 

AIT patent-pending solderable insulating lids and patented wafer level MEMS and optical lids solutions (US patent#6,432,253; 6,428,650; 6,409,859; 6,136,128) represent some of the most innovative solutions in lid sealing. The solderable lid seal when applied to insulating lids such as glass for optical lids, ceramic lids for large and small components, LCP (Liquid Crystal Polymers) for high performance components, and lid seals for MEMS and wafer level packaging represents the most cost-effective solution for reliability and performance:

◊     The only proven polymer lid-seal solution that passes fine and gross leak tests.
◊     Unparalleled high temperature stability to withstand soldering at 300°C.
◊     Ideal for high volume component lid sealing.
◊     Ideal for CCD and optical devices when glass lids are used.

 Preform Lid-Seal Solution and Process
1.      Send lid design to our sales-engineering staff
   ◊    It is most cost-effective if preforms are made in a panel or wafer with repeating devices
2.      Review and approve lid design 
3.      AIT manufactures B-staged adhesive preforms based on a repeating device pattern 
4.      Lids,panel or wafer of lids are placed onto adhesive preforms 
5.      Place lids with adhesive preforms onto devices
6.      Cure Lids onto devices
   ◊    Induce and observe flow of adhesive to cover lid perimeters
   ◊    AIT preforms are typically high flow to allow you to observe the sealing of all sides
7.      Excise devices
8.      Test for seals and other qualities
