Solder phala kusindikiza njira ya miniaturized zigawo zikuluzikulu 3-1

M'zaka zaposachedwa, pakuwonjezeka kwa zofunikira pakugwira ntchito kwa zida zamtundu wanzeru monga mafoni anzeru ndi makompyuta apakompyuta, makampani opanga ma SMT ali ndi kufunikira kwakukulu kwa miniaturization ndi kupatulira zida zamagetsi.Chifukwa cha kukwera kwa zida zovala, kufunikira uku kumakulirakulira.Mochulukira.Chithunzi chomwe chili pansipa ndikufanizira ma I-phone 3G ndi I-phone 7 motherboards.Foni yatsopano ya foni ya I-phone ndi yamphamvu kwambiri, koma bokosi la amayi lomwe linasonkhanitsidwa ndi laling'ono, lomwe limafunikira zigawo zing'onozing'ono ndi zowawa kwambiri.Msonkhano ukhoza kuchitidwa.Ndi zigawo zing'onozing'ono ndi zazing'ono, zidzakhala zovuta kwambiri pakupanga kwathu.Kupititsa patsogolo kuchuluka kwa kuchuluka kwakhala cholinga chachikulu cha akatswiri opanga ma SMT.Nthawi zambiri, kuposa 60% ya zolakwika mumakampani a SMT zimagwirizana ndi kusindikiza phala la solder, yomwe ndi njira yofunika kwambiri pakupanga kwa SMT.Kuthetsa vuto la solder phala kusindikiza ndi kofanana ndi kuthetsa mavuto ambiri ndondomeko mu lonse SMT ndondomeko.

    

Chithunzi chomwe chili pansipa ndi tebulo lofananiza la miyeso ya metric ndi mfumu ya zigawo za SMT.

Chithunzi chotsatira chikuwonetsa mbiri yachitukuko cha zigawo za SMT ndi chitukuko chomwe chikuyembekezera mtsogolo.Pakalipano, zipangizo za British 01005 SMD ndi 0.4 pitch BGA/CSP zimagwiritsidwa ntchito popanga SMT.Zida zazing'ono za metric 03015 SMD zimagwiritsidwanso ntchito popanga, pomwe zida za metric 0201 SMD pakadali pano zimangopanga zoyeserera ndipo zikuyembekezeka kugwiritsidwa ntchito pang'onopang'ono popanga zaka zingapo zikubwerazi.
