Yakakwira chaiyo PCBA redunhu bhodhi DIP plug-in yakasarudzika wave soldering welding dhizaini inofanirwa kutevedzera zvinodiwa!
Mune yechinyakare yemagetsi gungano maitiro, wave welding tekinoroji inowanzo shandiswa kukwenenzverwa kwezvinhu zvakadhindwa zvebhodhi zvine perforated kuisa zvinhu (PTH).
DIP wave soldering ine zvakawanda zvisingabatsiri:
1. High-density, fine-pitch SMD components haigone kugoverwa pane welding surface;
2. Kune akawanda mabhiriji uye anoshaikwa ekusodha;
3.Flux inoda kumwayiwa; bhodhi rakadhindwa rakamonyoroka uye rakakanganiswa nekuvhunduka kukuru kwemafuta.
Sezvo ikozvino dhizaini yegungano redunhu iri kuramba ichikwira uye ichikwira, hazvidzivirike kuti yakakwirira-density, yakanaka-pitch-pitch SMD zvikamu zvichagovaniswa pane soldering surface. Iyo yechinyakare wave soldering process yanga isina simba rekuita izvi. Kazhinji, zvikamu zveSMD pane soldering pamusoro zvinogona chete reflow kutengeswa zvakasiyana. , uye wozogadzirisa nemaoko zvakasara plug-in solder majoini, asi pane dambudziko rekushaya solder joint quality kuenderana.
Sezvo kushambadzira kwemukati-mugomba zvikamu (kunyanya-hombe-kugona kana yakanaka-pitch zvikamu) kunowedzera uye zvakanyanya kuoma, kunyanya kune zvigadzirwa zvine-isina-mutobvu uye yakakwirira kuvimbika zvinodiwa, iyo solder mhando yemanhamba soldering haichakwanise kusangana nemhando yepamusoro. midziyo yemagetsi. Zvinoenderana nezvinodiwa zvekugadzira, wave soldering haigone kuzadzisa kugadzirwa uye kushandiswa kwemabheti madiki uye akawanda marudzi mukushandiswa chaiko. Iko kushandiswa kwekusarudza wave soldering kwakakura nekukurumidza mumakore achangopfuura.
For PCBA redunhu mapuranga ane chete THT perforated zvinoriumba, nokuti wave soldering teknolojia ichiri inonyanya kushanda nzira pari zvino, hazvina zvakakodzera kutsiva wave soldering pamwe anosarudza soldering, izvo zvinokosha zvikuru. Nekudaro, yakasarudzika solder yakakosha kune yakasanganiswa tekinoroji mabhodhi uye, zvichienderana nerudzi rwenozzle inoshandiswa, wave soldering matekiniki anogona kudzokororwa nenzira inoyevedza.
Pane maitiro maviri akasiyana ekusarudza solder: dhonza solder uye dip soldering.
Iyo yakasarudzwa yekudhonza solder process inoitwa pane imwechete diki tip solder wave. Iyo yekudhonza solder process inokodzera solder panzvimbo dzakasimba kwazvo paPCB. Semuenzaniso: majoini ega ega solder kana mapini, mutsara mumwe chete wepini unogona kudhonzwa uye kutengeswa.
Selective wave soldering tekinoroji ichangoburwa tekinoroji muSMT tekinoroji, uye kutaridzika kwayo kunosangana zvakanyanya nezvinodiwa negungano repamusoro-density uye akasiyana akasanganiswa PCB mabhodhi. Selective wave soldering ine zvakanakira yekumisikidza yakazvimiririra ye solder joint paramita, kushomeka kwekupisa kuPCB, kushomeka kwekupfapfaidza, uye kuvimbika kwakasimba kwekutengesa. Zvishoma nezvishoma iri kuve yakakosha solder tekinoroji kune yakaoma PCBs.
Sezvatinoziva tese, iyo PCBA yedunhu bhodhi dhizaini nhanho inosarudza 80% yemutengo wekugadzira wechigadzirwa. Saizvozvowo, maitiro akawanda ehutano anogadziriswa panguva yekugadzira. Naizvozvo, zvakakosha kuti utarise zvizere kugadzira zvinhu muPCB redunhu bhodhi dhizaini maitiro.
Iyo yakanaka DFM inzira yakakosha yekuti PCBA inokwirisa chikamu vagadziri vaderedze kukanganisa kwekugadzira, kurerutsa maitiro ekugadzira, kupfupisa kutenderera kwekugadzira, kuderedza mutengo wekugadzira, kukwidziridza kutonga kwemhando, kuwedzera kukwikwidza kwemusika wechigadzirwa, nekuvandudza kuvimbika kwechigadzirwa uye kusimba. Inogona kugonesa mabhizinesi kuwana iwo akanakisa mabhenefiti neine mari shoma uye kuwana zvakapetwa kaviri mhedzisiro nehafu yekuedza.
Kuvandudzwa kwezvikamu zvekukwira pamusoro kusvika nhasi kunoda mainjiniya eSMT kwete kungove nehunyanzvi mudhizaini yedhizaini tekinoroji, asi zvakare kuve nekunzwisisa kwakadzama uye nehupfumi hunoshanda ruzivo muSMT tekinoroji. Nokuti mugadziri asinganzwisisi kuyerera maitiro e solder paste uye solder kazhinji zvakaoma kunzwisisa zvikonzero nemisimboti yebhiriji, tipping, tombstone, wicking, nezvimwewo, uye zvakaoma kushanda nesimba kugadzira padhi patani zvine musoro. Zvakaoma kubata neakasiyana dhizaini nyaya kubva pamaonero ekugadzira manufacturability, testability, uye mutengo uye kuderedzwa kwemari. Mhinduro yakanyatsogadzirwa inodhura yakawanda yekugadzira uye yekuedza mitengo kana iyo DFM neDFT (dhizaini yekuonekwa) isina kunaka.
