Uthini umahluko phakathi kwebhodi ye-epoxy ye-3240 kunye FR4 epoxy ibhodi?

1. Umbala oqaqambileyo.

Umbala webhodi ye-FR4 epoxy yendalo kakhulu, intwana yejeyidi, kwaye umbala webhodi ye-epoxy engama-3240 uyadanyaza kancinci. Akubonakali kwendalo. Uninzi lwemibala alufani ncam.

2. I-FR4 inokusebenza kakuhle kwe-flame retardant.

I-FR4 yimveliso ephuculweyo yebhodi ye-epoxy resin ye-3240. Ukusebenza kwe-flame retardant yebhodi ye-epoxy ye-FR4 idibana nomgangatho we-UL94V-0 wesizwe. Ibhodi ye-epoxy resin ye-3240 ayinayo iipropathi ze-flame retardant.

3. I-FR4 ayisebenzisi imitha kwaye ayihambelani nokusingqongileyo.

Ibhodi ye-epoxy resin ye-3240 i-halogen-equlethwe, engahambelani kakhulu nokusingqongileyo kunye nomzimba womntu. Kananjalo ayihambelani nesicwangciso-qhinga selizwe sophuhliso oluzinzileyo. Ibhodi ye-epoxy ye-FR4 ichasene nje.

4. I-FR4 inokuzicima ngokwayo emlilweni.

I-FR4 inokucinywa ngokwendalo xa kuvele umlilo.

5. I-FR4 inozinzo oluhle lwe-dimensional.

Uzinzo lwe-FR4 lungcono kunolo lwe-3240, kwaye ngexesha lenkqubo yokucinezela, ukunyamezelana kwe-FR4 kulunge ngakumbi kunoko kungama-3240, ekulungele ngakumbi ukuqhubekeka.

6. Ukufunxa amanzi aphantsi.

Ukufunxwa kwamanzi (D-24/23, ubukhulu beplate 1.6mm): ≤19mg, ebonelela ngoncedo olufanelekileyo ekusetyenzisweni kwayo kwisiguquli esimanzi nakwezinye izixhobo.
