Amanye amacandelo e-elektroniki kwiibhodi zeesekethe ezichanekileyo azikwazi ukugqunywa, ngoko ke umatshini wokugquma okhethiweyo kufuneka usetyenziselwe ukugquma ukuthintela amacandelo e-elektroniki angenako ukugqunywa ukuba angagqunywa nge-conformal coating.
I-Conformal anti-peyinti yimveliso yekhemikhali elulwelo esetyenziswa kwiibhodi zoomama zeemveliso ezahlukeneyo zombane.Ingafakwa kwi-motherboard ngebrashi okanye isitshizi.Emva kokunyanga, ifilimu encinci inokuqulunqwa kwi-motherboard.Ukuba indawo yokusetyenziswa kweemveliso ze-elektroniki inzima kakhulu, njengokufuma, ukutshiza ityuwa, uthuli, njl. njl., ifilimu iya kuzithintela ezi zinto ngaphandle, ivumela ukuba i-motherboard isebenze ngokuqhelekileyo kwindawo ekhuselekileyo.
Ipeyinti enobungqina obuthathu ikwabizwa ngokuba yipeyinti ekhusela ukufuma kunye nepeyinti yokugquma.Inomphumela wokugquma.Ukuba kukho iindawo ezisebenza ngamandla okanye iindawo ezidityanisiweyo ebhodini, ayinakupeyintwa ngepeyinti echasene ne-corrosion.
Ngokuqinisekileyo, iimveliso ze-elektroniki ezahlukeneyo zifuna iingubo ezahlukeneyo ezihambelanayo, ukuze ukusebenza kokukhusela kubonakaliswe ngcono.Iimveliso ze-elektroniki eziqhelekileyo zinokusebenzisa ipeyinti ehambelanayo ye-acrylic.Ukuba indawo yesicelo ifumile, i-polyurethane conformal paint ingasetyenziswa.Iimveliso ze-elektroniki ezikumgangatho ophezulu zinokusebenzisa ipeyinti ehambelana ne-silicone.
Ukusebenza kwepeyinti yobungqina obuthathu bubungqina bokufuma, ukuchasana nokubola, ukutshiza ityuwa, ukugquma, njl. usebenzisa i-conformal coating?
Ipeyinti yobungqina obuthathu isetyenziselwa ukhuseleko lwesibini kwiibhodi zeesekethe zeemveliso zombane.Ngokubanzi, umphandle webhodi ye-motherboard kufuneka ube neqokobhe ukuvimba inani elikhulu lokufuma.Ifilimu eyenziwe ngepeyinti yobungqina obuthathu kwi-motherboard kukuthintela ukufuma kunye nesitshizi setyuwa ekonakaliseni i-motherboard.ye.Ngokuqinisekileyo kufuneka sikhumbuze abasebenzisi.Ipeyinti enobungqina obuthathu inomsebenzi wokugquma.Kukho iindawo ezithile kwibhodi yesekethe apho ipeyinti echasene nebhatyi ingenakusetyenziswa.Izinto ezingenakupeyintwa ngepeyinti yebhodi yesekethe ehambelanayo:
1. Amandla aphezulu kunye neendawo zokulahla ukushisa okanye i-radiator, i-resistors yamandla, i-diodes yamandla, i-samente resistors.
2. Iswitshi ye-DIP, i-resistor ehlengahlengiswayo, i-buzzer, isibambi sebhetri, i-fuse holder (ityhubhu), i-IC holder, i-tact switch.
3. Zonke iintlobo zeesokethi, iintloko ze-pin, iibhloko ze-terminal kunye ne-DB headers.
4. I-plug-in okanye i-sticker-type light-emitting diodes kunye neetyhubhu zedijithali.
5. Ezinye iindawo kunye nezixhobo ezingavumelekanga ukuba zisebenzise ipeyinti ye-insulating njengoko kuchaziwe kwimizobo.
6. Imingxunya ye-screw yebhodi ye-PCB ayinakupeyintwa ngepeyinti echasene ne-conformal.
