FFC Cable Delamination Cause

One of the most common problems with flat flexible cables exposed to humidity is delamination

The cables manufactured with standard adhesive can absorb moisture with time

The main reason is that polyester and adhesive are porous. With humidity, the cable can absorb moisture. With time and elevated temperature, the moisture can expand and make the cable delaminated

When selecting FFC Vendors, it is important they use films with proven adhesives that withstand 85% of relative humidity at +85°C during 165 hours, according to UL standard
