A cikinPCBtaro da soldering tsari, SMT guntu sarrafa masana'antun da yawa ma'aikata ko abokan ciniki da hannu a ayyuka, kamar toshe-in saka, ICT gwajin, PCB tsagawa, manual PCB soldering ayyuka, dunƙule hawa, rivet hawa, crimp connector manual latsa, PCB keke, da dai sauransu, aikin da aka fi sani shine mutum daya ya dauko allo da hannu daya, wanda shine babban dalilin gazawar BGA da capacitors. To me yasa hakan ke haifar da rashin aiki? Bari editan mu ya bayyana muku shi a yau!
Hatsarin rike daPCBallo da hannu daya:
(1) Rike allon PCB da hannu ɗaya ana ba da izinin gabaɗaya don waɗancan allunan da'ira masu ƙananan girman, nauyi mai nauyi, babu BGA kuma babu ƙarfin guntu; amma ga waɗanda da'irori da babban size, nauyi nauyi, BGA da guntu capacitors a gefen allon, wanda ya kamata a kauce masa. Saboda irin wannan hali na iya haifar da haɗin gwiwa na BGA cikin sauƙi, ƙarfin guntu har ma da juriya ga guntu. Sabili da haka, a cikin takaddun tsari, ya kamata a nuna buƙatun yadda ake ɗaukar allon kewayawa.
Mafi sauƙi na riƙe PCB da hannu ɗaya shine tsarin zagayowar allo. Ko cire allo daga bel ɗin jigilar kaya ko sanya allo, yawancin mutane cikin rashin sani suna ɗaukar al'adar riƙe PCB da hannu ɗaya saboda ita ce mafi dacewa. Lokacin sayar da hannu, manna radiator kuma shigar da sukurori. Don kammala aiki, a zahiri za ku yi amfani da hannu ɗaya don sarrafa wasu abubuwan aiki a kan allo. Wadannan da alama ayyuka na yau da kullun suna ɓoye manyan haɗari masu inganci.
(2) Sanya skru. A yawancin masana'antun sarrafa guntu na SMT, don adana farashi, kayan aiki ba a barin su. Lokacin da aka shigar da sukurori a kan PCBA, abubuwan da ke bayan PCBA galibi suna lalacewa saboda rashin daidaituwa, kuma yana da sauƙi a fashe haɗin gwiwar solder mai damuwa.
(3) Saka abubuwan da aka haɗa ta cikin rami
Abubuwan da aka haɗa ta cikin ramuka, musamman masu canji masu kauri mai kauri, galibi suna da wahalar saka daidai a cikin ramukan hawa saboda girman matsayi na jagororin. Masu aiki ba za su yi ƙoƙari su nemo hanyar da za ta kasance daidai ba, yawanci suna amfani da aiki mai tsauri, wanda zai haifar da lanƙwasa da nakasar allon PCB, kuma zai haifar da lalacewar da ke kewaye da capacitors, resistors, da BGA.
