Gyinaesi Anan Wɔ Custom FPC Mu

A custom FPC LCD module te sɛ gyinaesi biako na ɛyɛ anan ankasa. Nea edi kan no, bend radius: bobɔ FPC no denneennen dodo na kɔbere no brɛ na ɛpaapae, a anyɛ yiye koraa no radius no taa yɛ ne kɛse mmɔho asia kosi du, enti ɛsɛ sɛ mfiri no nhyehyɛe no sie baabi a ɛwɔ no.

Nea ɛto so abiɛsa, nsateaa a ɛne ne ho di nkitaho: sika kɔkɔɔ a ɛyɛ den, carbon a wɔde kata so ne nea wɔde hyɛ mu no nyinaa di nkitahodi ahotoso so. Nea ɛto so anan, nkitahodi no ankasa: ɛnne, ne sorokɔ ne sɛ ebia ɛkyere.

Bend radius ne nea wɔtaa pa. Nnwuma ahorow piapia ɔyɛkyerɛ no kosi anohyeto bere a wɔde mfiri rehwɛ mu no, nhwɛsode no hyerɛn bere a wɔaboaboa ano no, na ahotoso sɔhwɛ no ba awiei wɔ ɔmansin a wɔabue mu.

Wɔ mfonini bi so no ɛyɛ gyinabea a nkyerɛwde biako wɔ; wɔ afuw mu no ɛyɛ sanba dodow no fã.
