I-Wave soldering ngisho ne-tin izimbangela nezindlela zokwelashwa

Umshini we-Wave solderingngisho ne-tin iyinkinga evamile ekukhiqizeni imikhiqizo ye-electronic plug-in wave soldering, ikakhulukazi ngenxa ye-wave soldering ngisho ne-tin ebangelwa izizathu ezihlukahlukene.Uma ufuna ukulungisa i-wave soldering ukuze unciphise ngisho ne-tin, kuyadingeka ukuthola izimbangela ze-wave soldering ngisho ne-tin.Lapha ukwabelana ngezimbangela kanye nemibono yokucubungula.

I-Wave soldering enezizathu zamathini.

1. Ukushisa kwe-Flux preheating kuphezulu kakhulu noma kuphansi kakhulu, ngokuvamile ku-100 ~ 110 degrees, ukushisa kuqala kuphansi kakhulu, umsebenzi we-flux awuphezulu.Ukushisa kuphezulu kakhulu, ku-tin steel flux akusekho, kodwa futhi kulula ngisho nokufaka ithini.
2. Akukho ukugeleza noma ukugeleza akwanele noma ukungalingani, ukungezwani okungaphezulu kwesimo esincibilikisiwe sikathini akukhululwa, okuholela ekubeni kube lula ngisho nokuthayela.
3. Hlola izinga lokushisa lesithando somlilo, lawula cishe ama-degree angama-265, kungcono ukusebenzisa i-thermometer ukukala izinga lokushisa kwe-wave crest lapho i-wave crest ishaya, ngoba inzwa yokushisa yemishini ingase ibe ngaphansi kwesithando somlilo. noma ezinye izindawo.Preheating lokushisa akwanele kuzoholela izingxenye ayikwazi ukufinyelela izinga lokushisa, inqubo Welding ngenxa ingxenye ukushisa ukumuncwa, okuholela abampofu Hudula tin, futhi ukwakheka ngisho tin.Kungase futhi kube nezinga lokushisa eliphansi lesithando sethayela, noma isivinini sokushisela sishesha kakhulu.
4. Ukuhlola njalo ukwenza ukuhlaziywa kwe-tin, kungenzeka ukuthi ithusi noma okunye okuqukethwe kwensimbi kudlula izinga, okuholela ekunciphiseni ukuhamba kwe-tin, okubangelwa kalula ngisho ne-tin.
5. Hlola i-engeli ye-wave soldering track, ama-degree angu-7 angcono kakhulu, aphansi kakhulu kulula ukulenga ithini.
6. I-IC kanye nomugqa wedizayini embi, kuhlanganiswe, izinhlangothi ezine ze-IC eziminyene kwesikhala sonyawo <0.4mm, ayikho i-engeli etshekile ebhodini.
7. PCB eshisisa usinki ophakathi deformation okubangelwa ngisho ithini.
8. Insimbi kathayela iphakeme kakhulu, eyokuqala idla ithini eningi, iwugqinsi kakhulu, kufanele ilingane.
9. Amaphedi webhodi lesifunda awaklanyelwe phakathi kwedamu le-solder, elixhunywe ngemva kokuphrinta ku-solder paste;noma ibhodi lesifunda ngokwayo yakhelwe ukuba solder idamu / ibhuloho, kodwa umkhiqizo osuphelile ibe ingxenye noma zonke off, ke futhi kulula ngisho tin.

I-Wave soldering ngisho nezindlela zokwelapha ithini.

1. I-Flux ayanele noma ayanele, yandisa ukugeleza.
2. I-United tin ukusheshisa iphoyinti lejubane, iphoyinti lokukhulisa i-engeli yethrekhi.
3. Ungasebenzisi igagasi elingu-1, elinamagagasi angu-2 wegagasi elilodwa, udle ukuphakama kwethini akudingekile ukuba kube yi-1/2, kungathinta nje phansi kwebhodi kwanele.Uma unethreyi, indawo kathini ethreyini evalwe indawo ephakeme kakhulu yinhle.
4. Ukuthi ibhodi likhubazekile.
5. Uma i-2 wave single hit ingeyinhle, nge-wave punch engu-1, igagasi elingu-2 lishaye kancane thinta izikhonkwane ezikulo, ukuze ukwazi ukulungisa ukwakheka kwejoyinti le-solder, ngaphandle kokuhle.
