Xakamaynta Saxda ah ee Heerkulka Foornada Dib-u-soo-celinta ee SMT si loo Horumariyo Tayada Alxanka
Dhibaato ma ku haysaa Xakamaynta Heerkulka Foornada Dib-u-socodka ah inta lagu jiro Soo-saarka? Heerkan Dejinta ayaa kaa caawin doona
Habka wax soo saarka ee SMT (Surface Mount Technology), saxnaanta xakamaynta heerkulka foornada dib-u-socodka ayaa si toos ah u go'aamisa tayada alxanka iyo waxqabadka badeecada elektaroonigga ah. Xitaa leexashooyin yar ayaa keeni kara cillado sida kala-goysyada alxanka qabow, godadka, ama dhaawaca qaybaha.
Shirkadda Korontada ee RICH FULL JOY, oo ku salaysan khibrad ballaaran oo wax soo saar PCBA ah iyo khibrad farsamo, ayaa soo saartay "Heerka Dejinta Muuqaalka Heerkulka Foornada ee Reflow," iyadoo bixinaysa tilmaamo cilmiyeed, nidaamsan, iyo wax ku ool ah oo loogu talagalay xakamaynta heerkulka foornada dib-u-socodka ee SMT.
Dulmar Guud oo Caadi ah
Heerkani wuxuu khuseeyaa dhammaan foornooyinka dib-u-warshadaynta ee aqoon-is-weydaarsigayaga SMT, iyadoo injineerada xirfadleyda ah ee SMT ay mas'uul ka yihiin dejinta iyo maaraynta astaamaha heerkulka si loo hubiyo xakamaynta heerkulka saxda ah inta lagu jiro alxanka.
Diyaarinta Qalabka
Si sax ah loo cabbiro loona dejiyo astaamaha heerkulka, qalabka soo socda ayaa loo baahan yahay: Tijaabiyaha PROFILE, fiilooyinka thermocouple, looxyada PCB ee dhabta ah ee cabbirka, galoofyada ilaalinta, iyo qeexitaannada koollada alxanka.
Dejinta Heerarka
1. Aasaaska Tixraaca
Deji xuduudaha sida heerka kor u qaadista, heerkulka hore u kululaynta, iyo heerkulka dib u socodka iyadoo lagu salaynayo sifooyinka laysarka alxanka ee kala duwan (tusaale ahaan, laysarka alxanka lead-ka lahayn, ee aan lahayn rasaas).
2. Aasaaska Cabbirka
Astaamaha heerkulka waa in lagu cabbiraa looxyada PCB-ga dhabta ah si sax ah loogu muujiyo saameynta jawiga wax soo saarka dhabta ah ee wareejinta kulaylka.
3. Heerarka Guud
· Heerka Sare u kaca: 1–4℃/s
· Aagga Hore ee Kulaylka: 150–200℃, 60–120s
· Aagga Dib-u-socodka: ≥220℃ muddo 30–60 sano ah
· Heerkulka ugu sarreeya: 235–250℃
· Heerka Qaboojinta:
4. Shuruudaha Gaarka ah
Hagaaji bogga si firfircoon iyadoo lagu saleynayo jawaab celinta tayada badeecada ama si adag u raac shuruudaha macaamiisha ee la habeeyey.
5.I-Xisaabaadka Daaweynta Xabagta
Heerkulka daaweynta gulukooska I waa 120 ℃, iyadoo wakhtiga bogsashada uu u dhexeeyo 90-150 ilbiriqsi, iyo xadka ugu badan ee 170 ℃.
Ka taxadaritaan
1. Tijaabin Maalinle ah
Tijaabo heer-kulul oo dhammaystiran waa in la sameeyaa oo la duubaa ka dib marka la shido korontada ama khadka wax soo saarka maalin kasta.
2. Hay'adda Hawlgalka
Kaliya injineerada SMT ee xirfadlayaasha ah ayaa loo oggol yahay inay wax ka beddelaan dejimaha astaanta heerkulka.
3. U hoggaansanaanta Tilmaamaha Macaamilka
Si adag u deji xuduudaha habka iyadoo loo eegayo shuruudaha dib-u-socodka ee macaamiisha ay cayimeen.
4. Dayactirka Qalabka
Samee tijaabooyin ku saabsan hawo-mareenka nidaamka qiiqa ee foornada dib-u-socodka lixdii biloodba mar, adigoo hubinaya in si deggan loo shaqeeyo. Kala duwanaanshaha heerkulka ee u dhexeeya aagagga waa inaysan ka badnaan 70℃.
Gunaanad
Iyadoo la hirgelinayo "Heerka Dejinta Heerka Heerkulka Foornada ee Dib-u-cusboonaysiinta," RICH FULL JOY Electronics waxay hubineysaa alxanka SMT ee tayo sare leh, waxay wanaajisaa isku halaynta wax soo saarka iyo waxqabadka badeecada, waxayna ka caawisaa macaamiisha inay dardargeliyaan waqtiga suuqa iyo inay helaan faa'iidooyin tartan ah.
