Masitepe opangira ma wave soldering ndi mfundo kuti azisamalire.

1. Njira zogwirira ntchito zamakina opangira ma wave soldering.

1).Zida zopangira mafundekukonzekera pamaso kuwotcherera
Onani ngati PCB kuti soldered ndi yonyowa, ngati solder olowa ndi oxidized, olumala, etc.;Flux imalumikizidwa ndi mawonekedwe a nozzle a sprayer.

2).Kuyamba kwa zida zopangira ma wave soldering
Sinthani m'lifupi mwa lamba woyendetsa makina ozungulira (kapena mawonekedwe) malinga ndi m'lifupi mwa bolodi losindikizidwa;Yatsani mphamvu ndi ntchito ya fani iliyonse yamakina ozungulira.

3).Khazikitsani magawo owotcherera a zida zowotchera zowotcherera
Flux Flow: Kutengera momwe flux imalumikizira pansi pa PCB.Flux imafunika kuti ikhale yokutidwa mofanana pansi pa PCB.Kuyambira padzenje pa PCB, payenera kukhala kakuchulukira pang'ono pamwamba pa dzenje lolowera kuchokera padzenje kupita pa pad, koma osalowa.

Kutentha kwa preheating: kutengera momwe zinthu zilili mu uvuni wa microwave preheating zone (kutentha kwenikweni pamtunda wa PCB nthawi zambiri kumakhala 90-130 ° C, kutentha kwa mbale yakuda ndi malire apamwamba a bolodi lomwe linasonkhana ndi zambiri. zigawo za SMD, ndi kutentha kukwera kotsetsereka kumakhala kochepa kapena kofanana ndi 2 ° C / S;

Kuthamanga kwa lamba wa conveyor: malinga ndi makina osiyanasiyana opangira mafunde ndi ma PCB kuti agulitsidwe (nthawi zambiri 0.8-1.60m/min);kutentha kwa solder: (kuyenera kukhala kutentha kwenikweni komwe kumawonetsedwa pa chida (SN-Ag-Cu 260±5℃, SN-Cu 265±5°C). kapena LCD ndi pafupifupi 3 ° C kuposa kutentha kwenikweni;

Kuyeza kutalika kwa nsonga: ikadutsa pansi pa PCB, sinthani mpaka 1/2 ~ 2/3 ya makulidwe a PCB;

Kuwotcherera angle: kutengera kutengera: 4.5-5.5 °;kuwotcherera nthawi: zambiri 3-4 masekondi.

4).Chogulitsacho chiyenera kugulitsidwa ndikuwunikiridwa (pambuyo pazigawo zonse zowotcherera zimafika pamtengo wokhazikitsidwa)
Pang'ono pang'ono ikani bolodi losindikizidwa pa lamba wotumizira (kapena makina), makinawo amangopopera nthiti, kutentha, ma solders ndi kuzizira;bolodi losindikizidwa limalumikizidwa pakutuluka kwa soldering yoweyula;malinga ndi muyezo woyendera fakitale.

5).Sinthani magawo owotcherera malinga ndi zotsatira zowotcherera za PCB

6).Chitani mosalekeza kupanga kuwotcherera, kulumikiza bolodi losindikizidwa dera pa kubwereketsa soldering yoweyula, anaika mu odana malo amodzi zolowa bokosi pambuyo anayendera, ndi kutumiza bolodi yokonza kuti wotsatira processing;panthawi yowotcherera mosalekeza, bolodi lililonse losindikizidwa liyenera kuyang'aniridwa, ndipo zolakwika zowotcherera matabwa osindikizidwa kwambiri ayenera kugulitsidwanso nthawi yomweyo.Ngati pali zolakwika pambuyo kuwotcherera, chifukwa chake chiyenera kudziwitsidwa, ndipo kuwotcherera kuyenera kupitilira mutatha kusintha magawo.

2. Mfundo za chidwi mu ntchito yoweyula soldering.

1).Pamaso yoweyula soldering, fufuzani mmene ntchito zida, khalidwe la osindikizidwa dera bolodi kuti soldered ndi pulagi-mu udindo.

2).Pamene mukuwotchera mafunde, nthawi zonse muyenera kulabadira ntchito ya zida, kuyeretsa oxides pamwamba pa bafa malata mu nthawi, kuwonjezera polyphenylene efa kapena Sesame mafuta ndi antioxidants ena, ndi kudzaza solder mu nthawi.

3).Pambuyo pakuwotchera, mtundu wa kuwotcherera uyenera kuyang'aniridwa ndi block ndi block.Pazinthu zochepa zomwe zikusowa soldering ndi bridging soldering point, kuwotcherera pamanja kuyenera kuchitika panthawi yake.Ngati pali zovuta zambiri zowotcherera, fufuzani zifukwa munthawi yake.

Wave soldering ndi njira yokhwima yopangira mafakitale.Komabe, ndi kuchuluka kwa ntchito zopangira zida zapamtunda, njira yophatikizira yophatikizika ya zida zamapulagi ndi zigawo zokwera pamwamba zomwe zimasonkhanitsidwa pa bolodi loyang'anira dera nthawi yomweyo zakhala mawonekedwe a msonkhano wamba muzinthu zamagetsi, motero zimapereka magawo ambiri azinthu. kwa ukadaulo wa wave soldering.Kuti akwaniritse zofunika kwambiri, anthu akupitirizabe kufufuza njira zowonjezera zowonjezera zowonjezera zowonongeka, kuphatikizapo: kulimbikitsa kulamulira kwapamwamba kwa mapangidwe osindikizira a bolodi ndi zigawo zisanayambe kugulitsidwa;kupititsa patsogolo zipangizo monga kusinthasintha ndi solder Quality Control;pa ndondomeko kuwotcherera, kukhathamiritsa magawo ndondomeko monga kutentha preheating, kuwotcherera njanji kulolera, yoweyula kutalika, kuwotcherera kutentha ndi zina zotero.
