Dab tsi yog cov haujlwm ntawm FR4 Epoxy Board?

1. Various forms:

Ntau yam resins, curing agents, thiab modifier systems yuav luag hloov mus rau qhov yuav tsum tau ntawm ntau yam kev siv ntawm daim ntawv, thiab qhov ntau yuav yog los ntawm tsawg viscosity mus rau siab melting point solids.

2. Convenient curing:

Xaiv ntau yam tshuaj tua kab mob sib txawv, cov txheej txheem epoxy resin tuaj yeem yuav luag kho tau hauv qhov kub ntawm 0 ~ 180 ℃.

3. Low shrinkage:

Cov tshuaj tiv thaiv ntawm epoxy resin thiab tus neeg sawv cev kho siv yog ua los ntawm cov tshuaj tiv thaiv ncaj qha los yog lub nplhaib-qhib polymerization cov tshuaj tiv thaiv ntawm epoxy pawg nyob rau hauv cov molecule resin, thiab tsis muaj dej los yog lwm yam khoom los ntawm cov khoom tsis haum. Piv nrog unsaturated polyester resins thiab phenolic resins, lawv pom tsawg heev shrinkage (tsawg dua 2%) thaum kho.

4. Strong adhesion:

Lub hauv paus ntsiab lus ntawm polar hydroxyl pawg thiab ether bonds nyob rau hauv cov saw molecular ntawm epoxy resins ua rau nws nplaum heev rau ntau yam khoom. Lub shrinkage ntawm epoxy resin yog tsawg thaum kho, thiab cov kev ntxhov siab sab hauv tsim yog me me, uas kuj pab txhim kho lub zog adhesion.

5. Mechanical properties:

Cov kho epoxy resin system muaj cov cuab yeej zoo heev.
