Yini imisebenzi ye- Ibhodi le-epoxy le-FR4?

1. Amafomu ahlukahlukene:

Ama-resin anhlobonhlobo, ama-ejenti alaphayo, kanye nezinhlelo zokulungisa zingacishe zivumelane nezidingo zezinhlelo zokusebenza ezahlukahlukene efomini, futhi ububanzi bungaba ukusuka ku-viscosity ephansi kakhulu ukuya kokuqinile kwendawo yokuncibilika.

2. Ukwelashwa okulula:

Khetha izinhlobonhlobo zama-ejenti okwelapha ahlukene, uhlelo lwe-epoxy resin lungacishe lwelapheke ebangeni lokushisa elingu-0 ~ 180 ℃.

3. Ukuncipha okuphansi:

Ukusabela phakathi kwe-epoxy resin kanye ne-ejenti yokwelapha esetshenziswayo kwenziwa ngokusabela kokwengezwa okuqondile noma ukusabela kwe-polymerization yokuvula indandatho yamaqembu e-epoxy ku-molecule ye-resin, futhi awekho amanzi noma eminye imikhiqizo eguqukayo ekhishwayo. Uma kuqhathaniswa nezinhlayiya ze-polyester ezingasetshenzisiwe kanye nama-phenolic resins, abonisa ukuncipha okuphansi kakhulu (ngaphansi kuka-2%) ngesikhathi sokwelashwa.

4. Ukunamathela okuqinile:

Amaqembu e-polar hydroxyl namabhondi e-ether ochungechungeni lwamangqamuzana e-epoxy resins awenza anamathele kakhulu ezintweni ezihlukahlukene. Ukuncipha kwe-epoxy resin kuphansi lapho uphulukisa, futhi ukucindezeleka kwangaphakathi okukhiqizwa kuncane, okusiza futhi ukuthuthukisa amandla okunamathela.

5. Izakhiwo zemishini:

Uhlelo lwe-epoxy resin olulahliwe lunezici ezinhle kakhulu zemishini.
