Umahluko phakathi kwebhodi ye-epoxy engama-3240 kunye nebhodi ye-epoxy ye-FR4

Ibhodi epoxy engama-3240 kunye nebhodi ye-epoxy ye-FR4 zezona bhodi ze-epoxy zixhaphakileyo ezisetyenziswayo ngoku kwimarike. Wonke umntu uthi i-FR4 ingcono kunama-3240. Uyintoni umahluko phakathi kwabo?

Umahluko 1: i-FR4 inentsebenzo entle yedangatye.

I-FR4 yimveliso ephuculweyo yebhodi ye-epoxy engama-3240. Ukusebenza kokudangatye kwelangatye kwebhodi ye-epoxy ye-FR4 kuyahlangabezana nomgangatho we-UL94V-0 wesizwe. Ibhodi ye-epoxy engama-3240 ayinazipropati zedangatye.

Umahluko 2: Umbala oguqukayo.

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

Umahluko 3: i-FR4 ayisiyi-radiation kwaye inobuhlobo kwindalo.

Ibhodi ye-epoxy engama-3240 ine-halogen-equlathe, engenabungani kwindalo esingqongileyo kunye nomzimba womntu. Oku akuhambelani nesicwangciso esiliqili sophuhliso oluzinzileyo lwelizwe. Ibhodi ye-epoxy ye-FR4 yahlukile.

Umahluko 4: i-FR4 inokuzinza okuhle.

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

Umahluko wesihlanu: i-FR4 inokucima umlilo.

I-FR4 inokucinywa ngokwendalo xa kuvele umlilo.

Umahluko wesithandathu: ukufakwa kwamanzi asezantsi.

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

Ngenxa yokuba ibhodi ye-e-epoxy ye-FR-4 inentsebenzo elungileyo, ngoku isisxhobo sokufaka ubushushu kumashishini ombane nawombane. Ewe, ibhodi ye-epoxy engama-3240 isenentengiso ethile ngenxa yexabiso layo.
