Yintoni imisebenzi ye FR4 epoxy ibhodi?

1. Iindlela ezahlukeneyo:

Iintlaka ezahlukeneyo, ii-arhente zokunyanga, kunye neenkqubo zokulungisa zingaphantse zilungele iimfuno zezicelo ezahlukeneyo kwifomu, kwaye uluhlu lunokuba lusuka kwi-viscosity ephantsi kakhulu ukuya kwizinto eziqinileyo eziphezulu zokunyibilika.

2. Unyango olulula:

Khetha iindidi ezahlukeneyo zokunyanga, inkqubo ye-epoxy resin iphantse yanyangeka kuluhlu lobushushu obuyi-0 ~ 180 ℃.

3. Ukushwabana okuphantsi:

Ukusabela phakathi kwe-epoxy resin kunye ne-agent ephilisayo esetyenzisiweyo iqhutywa ngokuphendula ngokuthe ngqo kokongeza okanye ukuvuleka kwe-ring-opening reaction reaction of epoxy groups kwi-resin molekyuli, kwaye akukho manzi okanye ezinye iimveliso eziguqukayo ezikhutshwayo. Xa kuthelekiswa neentyantyambo ze-polyester ezingaxutywanga kunye ne-phenolic resins, zibonisa i-shrinkage ephantsi kakhulu (ngaphantsi kwe-2%) ngexesha lokunyanga.

4. Ukuncamathela okuqinileyo:

Amaqela endalo epolar hydroxyl kunye neebhondi ze-ether kwikhonkco lemolekyuli yeeresin ze-epoxy ziyenza incamathele kakhulu kwizinto ezahlukeneyo. I-shrinkage ye-epoxy resin iphantsi xa iphilisa, kwaye uxinzelelo lwangaphakathi olwenziwe luncinci, olunceda ekuphuculeni amandla okubambelela.

5. Iipropati zoomatshini:

Inkqubo ye-epoxy resin ephilileyo ineempawu ezibalaseleyo zoomatshini.
