Ma board amitundu yambiri | Assembly ndi kuwotcherera khalidwe | kuwotcherera ming'alu | kuchepa kwa thupi

Kodi mungatsimikizire bwanji kuti ma board amitundu yambiri akuwotcherera ndi abwino komanso kupewa ming'alu yowotcherera ndi zovuta zokhetsa?

Pomwe kufunikira kwa zida zamagetsi kukupitilira kukula, kufunikira kwa matabwa odalirika komanso apamwamba kwambiri amitundu yambiri kwakhala kofunikira. Ma board ozungulirawa amagwira ntchito yofunika kwambiri powonetsetsa kuti zida zamagetsi zikuyenda bwino. Komabe, panthawi ya msonkhano ndi kuwotcherera matabwa a madera osiyanasiyana, ngati sakusamalidwa bwino, mavuto monga kuwotcherera ming'alu ndi kupukuta mapepala amatha kuchitika. Mu positi iyi yabulogu, tikambirana njira zogwirira ntchito zowonetsetsa kuti ma board a board amitundu yambiri ndi soldering komanso kupewa kuti mavutowa asachitike.

Capel ndi kampani yomwe ili ndi zaka 15 zachidziwitso cha polojekiti komanso luso laukadaulo lamakampani. Ndi gulu lolimba komanso makina abwino kwambiri odzipangira okha, akhala opanga odalirika pamsika. Maluso awo okhwima komanso apamwamba kwambiri ophatikizika ndi luso lapamwamba la njira zimawathandiza kupanga ma board apamwamba, ogwira ntchito zambiri.

Pofuna kuwonetsetsa kuti ma board ozungulira ma multilayer amayenda bwino komanso kuwotcherera, njira zotsatirazi ziyenera kutsatiridwa:

1. Sankhani zinthu zoyenera:Kusankha zinthu ndizofunikira kwambiri pakuzindikira mtundu wonse wa board board. Sankhani zida zapamwamba zomwe zimakwaniritsa zofunikira. Izi zidzathandiza kupewa mavuto okhudzana ndi ming'alu ya solder ndi pad detachment.

2. Kuwongolera pamlingo uliwonse:Khazikitsani dongosolo lamphamvu lowongolera khalidwe lomwe likukhudza gawo lililonse lazinthu zopangira. Izi zikuphatikizapo kuyang'ana zipangizo zomwe zikubwera, kuyang'anira ndondomeko yopangira ndi kuyesa bwino mankhwala omaliza. Kuyang'ana pafupipafupi kungathandize kuzindikira zolakwika zilizonse kapena zovuta zomwe zingachitike msanga, kuchepetsa kuthekera kwa ming'alu ya solder ndi zovuta zapad.

3. Kusunga ndi kasamalidwe koyenera:Kusungirako bwino ndi kusamalira matabwa ozungulira n'kofunika kwambiri kuti akhalebe okhulupirika. Onetsetsani kuti matabwa ozungulira amasungidwa pamalo olamulidwa ndi chinyezi chokwanira komanso kutentha. Agwireni mosamala kuti apewe kuwonongeka kwakuthupi komwe kungapangitse ming'alu ya solder kapena ma pads kugwa.

4. Mapangidwe ndi masanjidwe olondola:Tsatirani ndondomeko zamapangidwe amakampani kuti muwonetsetse kuti board ikugwira ntchito moyenera komanso yodalirika. Mapangidwe opangidwa bwino amatha kuchepetsa kupsinjika pazigawo panthawi ya msonkhano ndi kuwotcherera, potero kuchepetsa mwayi wosweka kapena kutsekeka.

5. Njira zabwino zolumikizirana:Gwiritsani ntchito njira zoyenera zolumikizirana zomwe zimagwirizana ndi zofunikira za bolodi. Ganizirani zinthu monga kukula kwa gawo, njira ya soldering ndi mbiri ya reflow kuti muwonetsetse kuti pali mgwirizano wolimba komanso wodalirika wa solder. Kuwongolera kutentha koyenera pakuwotcherera ndikofunikira kuti mupewe kusweka ndi kusenda.

6. Kuyesa kwathunthu:Kuyesa kwathunthu kwa gulu ladera lomwe lasonkhanitsidwa kuti litsimikizire magwiridwe antchito ake ndi mtundu wake. Izi zikuphatikizapo kuyesa magetsi, kuyesa ntchito ndi kuyesa kudalirika. Kuyesa kumathandizira kuzindikira zovuta zilizonse zomwe zingachitike pakusokonekera ndi kugulitsa kotero kuti njira zowongolera zitha kuchitidwa bolodi isanafike kwa wogwiritsa ntchito.

Potsatira malangizowa, opanga amatha kusintha kwambiri khalidwe la msonkhano wamagulu ambiri ndi soldering. Njira yolimba ya Capel yokhudzana ndi zochitika za board board imawonetsetsa kuti njira zawo zopangira zimakonzedwa kuti zipangitse matabwa apamwamba kwambiri komanso kuchepetsa kuthekera kwa ming'alu ya solder ndi zovuta zopeka pad.

Powombetsa mkota,kuonetsetsa kuti msonkhano ndi soldering wa matabwa angapo oyendera dera ndizofunikira kwambiri pa ntchito yonse ndi kudalirika kwa zipangizo zamagetsi. Potsatira njira zomwe zili pamwambazi ndikusankha wopanga wodalirika wodziwa zambiri monga opanga Capel akhoza kuchepetsa chiopsezo cha ming'alu ya soldering ndi pad detachment. Kuyika ndalama pazinthu zamtengo wapatali, kugwiritsa ntchito machitidwe amphamvu owongolera, komanso kugwiritsa ntchito njira zolumikizirana bwino ndikofunikira kuti mupange ma board odalirika komanso olimba amitundu yambiri.
