Flexible flat cable (FFC) ngu ai gaw, n-gun n rawng ai n-gun rawng ai n-gun hte n-gun rawng ai arung arai ni hte hpawng de da ai, grai n-gun rawng ai electronic matut mahkai lam re. Electronic jak ni kata na signal hte power hpe htawt sit ai lam hta grai lang ai.

FFC a madung daw ni hta conductor layer, n-gun n rawng ai substrate, makawp maga ai layer ni lawm ai. Dai conductor hpe laksan hku nna, n-gun ja ai electrolytic magri (sh) tinned magri foil hte galaw nna, hkrak hkrak shinggrup ai (sh) shinggrup ai ladat hku nna, n-gun n rawng ai conductor array langai hku nna galaw ai. Line galu kaba ai hte tsan gang ai lam hpe application ra ai hte maren gram lajang mai ai, 0.5mm kaw nna 5mm du hkra lang ai common range ni nga ai.

Dai n-gun hpe madi shadaw ya ai ahkyak ai arung arai langai rai nna, n-gun hpe polyimide (PI) shing nrai polyester (PET) film hte galaw da ai. Polyimide gaw high-end application ni a matu grau ra sharawng ai lata la ai lam rai nna, shi a -temperature hpe hkam sharang lu ai (260℃du hkra aten galu-lang lang na matu) hte chemical hpe hkam sharang lu ai majaw rai nna, polyester gaw manu n law ai hte n-gun kaja ai majaw, htunghking makau grup yin ni hta htuk manu ai. Dai insulation layer gaw 0.05mm kaw nna 0.15mm du hkra galu nna, conductor layer hpe heat pressing (sh) adhesives hku nna ngang ngang jum da ra ai, dai hku galaw yang, insulation a bungli galaw lu na matu, yawng hkra hpe n-gun n rawng hkra galaw lu na re.
Multi-layer structures ni hta, FFC ni hta shielding layers (sh) n-gun shaja ai plate ni hpe bang nna, wan n-gun n-gun (EMI) hpe ninghkap lu ai atsam hpe jat ya lu ai (sh) jak hte madi shadaw ya lu ai.
