- Me yasa bukatar yin kwamitin?
Bayan ƙirar PCB, ya kamata a shigar da SMT a kan babban taron don haɗe kayan haɗin. Dangane da bukatun sarrafawa na layin taro, kowane masana'antar SMT na SMT zai tantance mafi dacewa girman hukumar da'ira. Misali, idan girman ya yi ƙarami ko babba, gyaran don gyara PCB akan gidan taron za a iya gyara.
Don haka idan girman PCB ɗin da kansa ya fi girman ƙimar da masana'anta ke ƙayyade? Wannan yana nufin muna buƙatar yanki tare da allunan da'irar, yawancin allon yanki da yawa zuwa yanki ɗaya.both don babban - saurin motsi na iya haɓaka haɓaka.

B. PCB tare da girman Bidaya Kasa da 100mm × 70mm za a tattarawa
2) sifar marasa daidaituwa don PCB
PCB tare da siffar da ba tare da izini ba kuma ya kamata a ƙara akwatin kwamitin na Panel tare da tsiri. Idan akwai rami a kan PCB mafi girma fiye da ko daidai yake da 5mm × 5mm, ya kamata a gama ramin farko a cikin ƙira don guji lalata mantineer da farantin. Kashi na ƙarshe da na asali PCB bangare ya haɗa ta da maki da yawa a gefe ɗaya kuma cire bayan sallar kalaman.
Lokacin da haɗi tsakanin tsararre da PCB shine V-daddara tsararre, nisa tsakanin gefen tsari kuma PCB ɗin da aka shirya a cikin 2mm na murfin hatimi.
3.The Panel
Hakkin kwamitin za a tsara shi cikin layi daya zuwa ga gefen watsawa, ban da girman "V-yanke" ko daidai da layin "V-yanke da ya zama ƙasa ko daidai da na bakin ciki da bakin ciki da bakin ciki
Na kwamiti na musamman, kula da haɗi tsakanin jirgi da jirgin-jirgin sama, yi ƙoƙarin yin haɗin kowane mataki daban a cikin layi.
4.Sana bayanin kula na PCB kwamitin
Gabaɗaya, samarwar PCB zai aiwatar da abin da ake kira aikin da ake kira haɓaka don ƙara ƙarfin samarwa na samar da samarwa. Menene cikakkun bayanai ya kamata a mai da hankali ga taron PCB? Da fatan za a duba waɗanda ke ƙasa:
1) The na waje frame (clamping gefen) na PCB Kwamitin za a tsara shi a cikin rufaffiyar madauki don tabbatar da cewa PCB Kwallan ba zai tsoratar da shi ba lokacin da aka gyara zuwa ga tsayayye.
2) Kyakkyawan fasalin PCB yana buƙatar murabba'in kamar yadda zai yiwu, da shawarar amfani da 2 × 2, 3, 3 × 3, ... Panels, amma babu mai bambanta agogo (YIN-Yang).
3) Faɗin girman Panel ≤260m (layin Siemens) ko ≤300mm (layin Fuji). Idan buƙatar buƙatar yin ta atomatik ba, faɗin x tsawon ≤125mm × 180mm ga girman Panel.
4) Kowane karamin katako a cikin kwamiti na PCB zai sami ramuka guda uku, rami diamita na 3 30, wiring ko smp ba a yarda a cikin 1mm na gefen kayan aikin koke.
5) Distance ta tsakiyar tsakanin ƙaramin katako ya kamata a sarrafa tsakanin 75mm da 145mm.
6) Lokacin saita rami mai amfani da kayan aiki, ya zama ruwan dare don barin yankin Welding na buɗe 1.5mm mafi girma a kusa da ramin kayan aikin.
7) Ba a sami manyan na'urori ko na'urori masu hawa ba kusa da batun haɗin tsakanin firam na waje da na ciki da kwamitin. Bayan haka, ya kamata fiye da 0.5mm sarari tsakanin abubuwan haɗin da gefen PCB Hukumar don tabbatar da aikin al'ada na kayan yankan yankan.
8) Four tooling holes with an hole diameter of 4mm±0.01mm were opened at the four corners of the outer frame of the panel.The strength of the hole should be moderate to ensure that it will not break during the process of upper and lower plate;Aperture and position accuracy should be high, the hole wall smooth without burr.
9) A manufa, QFP tare da jerawa ƙasa da 0.65mmm ya kamata a saita shi a cikin matsayin na Deagonal.The madadin da aka yi amfani da shi don taron za a yi amfani da taron.
10) Manyan abubuwa masu girma zasu sami wuraren aikawa ko ramuka, kamar ni / o Murmy, makirai, Jack, Motsa, da sauransu.
