I ka ʻoihana uila, loaʻa ka hana PCBA no nā lako polokalamumīkini hoʻoheheʻe nalua me ka wili lima lima.He aha nā ʻokoʻa ma waena o kēia mau ʻano hoʻoheheʻe ʻelua, he aha nā mea maikaʻi a me nā pōʻino?
I. Haʻahaʻa loa ka maikaʻi a me ka maikaʻi o ka welding
1. Ma muli o ka hoʻohana ʻia ʻana o ERSA, OK, HAKKO a me ka māwae a me nā mea ʻē aʻe kiʻekiʻe kiʻekiʻe naʻauao uila hao, ua hoʻomaikaʻi ʻia ka maikaʻi o ka wiliwili, akā aia kekahi mau mea paʻakikī ke kāohi.No ka laʻana, ʻo ka nui solder a me ka welding wetting ʻO ka mana Angle, ka hoʻopaʻa ʻana i ka paʻa ʻana, nā koi o ka helu tin ma o ka lua metallized.ʻOi loa i ka wā i uhi ʻia ke alakaʻi ʻāpana i ke gula, pono e wehe i ke gula a me ka lining tin no ka ʻāpana e pono ai ka hoʻoheheʻe tin-lead ma mua o ke kuʻi ʻana, he mea pilikia loa.
2. Loaʻa i ka wili lima nā kumu kanaka a me nā hemahema ʻē aʻe, paʻakikī ke hoʻokō i nā koi o ke kūlana kiʻekiʻe;No ka laʻana, me ka piʻi ʻana o ka mānoanoa o ka papa kaapuni a me ka hoʻonui ʻana i ka mānoanoa o ka papa kaapuni, piʻi ka nui o ka wela welding, maʻalahi ka wili hao hao e alakaʻi i ka wela ʻole, ka hoʻokumu ʻana o ka welding virtual a i ʻole ma o ka piʻi ʻana o ka lua. ʻaʻole kūpono ke kiʻekiʻe i nā koi.Inā hoʻonui nui ʻia ka mahana kuʻi a hoʻolōʻihi ʻia ka manawa kuʻi, maʻalahi ke hōʻino i ka papa kaapuni i paʻi ʻia a hāʻule ka pad.
3. Pono ka hao hao kuʻuna i nā poʻe he nui e hoʻohana i ka wiliwili kikoʻī ma ka PCBA.Hoʻohana ʻia ka hoʻoheheʻe ʻana i ka nalu koho, a laila hoʻomaʻamaʻa mua i ka papa kaapuni/flux, a laila hoʻohana i ka nozzle wili no ke ʻano kuʻi.Hoʻohana ʻia ke ʻano hana ʻoihana hui o ka laina hui.Hiki ke wiliwili ʻia nā nozzles welding o nā ʻano like ʻole i nā pūʻulu ma ke kauo ʻana.ʻO ka hana hoʻoheheʻe ʻana he mau haneli mau manawa kiʻekiʻe ma mua o ka wili lima.
II.Kuʻi ʻana o nā nalu o ke ʻano kiʻekiʻe
1. hiki ke "ho'olikelike 'ia" ke ka'ina hana i kēlā me kēia wahi ku'i 'ana, e like me ke kahe o ka nui, ka manawa ku'i, ke ki'eki'e o ka nalu a me ke ki'eki'e o ka nalu. , hiki ke hoemi nui ia na hemahema ma o na mea hole no ka wiliwili ana, O ka helu defect (DPM) o ka hoolele hawewe koho, oia ka haahaa loa i ka hoohalikeia ana me ka hoolele lima lima, ka hoolewa hou ana ma ka lua a me ke kuai nalu ma'amau.
2. wili nalu ma muli o ka hoʻohana 'ana o programmable mobile liʻiliʻi tin cylinder a me nāʻano likeʻole wili kuʻihao nozzle, no laila, i loko o ka welding kaʻina hiki ke programmed e pale aku i kekahi paʻa wili a me ka hoʻoikaika 'ana i nā wahi o KA PCB B aoao, i ole e hoʻopili i ka. kiʻekiʻe wela solder a hoʻopōʻino, ʻaʻohe pono e hoʻopilikino i ka pā welding a me nā ala ʻē aʻe.
3. Mai ka hoʻohālikelike ʻana ma waena o ka wili nalu a me ka wili lima, hiki iā mākou ke ʻike he nui nā pōmaikaʻi o ka wili nalu e like me ka maikaʻi o ka wiliwili maikaʻi, ka maikaʻi kiʻekiʻe, ka maʻalahi ikaika, ka haʻahaʻa haʻahaʻa haʻahaʻa, ka liʻiliʻi o ka pollution a me ka ʻokoʻa o nā mea wili.
