I. Di tin dɛn we kin mek Sabstret Wrinkling ɛn Adhesive Transfer

Substrate Wrinkling Di rut kɔz de pan di ɔt ɛn prɛshɔn distribyushɔn we nɔ ivin. FPC na mכltipכl mεtirial dεm lεk PI film, kכpa fכyl εn adeziv wit difrεn kכfishεnt dεm fכ tεmral εkspεns (CTE). Apat frɔm dat, sɔrkwit bɔd dizayn faktɔ dɛn inklud kɔpa tik we nɔ ivin ɛn stifin stɛp dɛn go mek di prɛshɔn distribyushɔn nɔ ivin. כt εn prεshכn we nכ yunifכm de mek intanεt mεtirial strεs, we de rεsult in wrinkling, wכp εn delamination.

Adhesive Transfer (Residual Adhesive) Dis kin bi bikɔs ɔf intafɛs ɛn matirial difrɛns. Di semi-cured adhesive of cover film fɔ lamination de mɛlt ɛn flɔ ɔnda ay tempɔret, ɛn adhere to di surface of isolation materials.
