Solder Creeping Impamvu & Ibisubizo bya PTFE Ubushyuhe bwo hejuru

Nkumushinga wumwuga ukora PTFE imyenda yubushyuhe bwo hejuru, Jiangsu Aokai Ibikoresho bishya bisangiye inganda zumwuga ubushishozi.Mu PCB igurisha ikirere gishyushye kuringaniza, isahani ya zahabu hamwe na zahabu yibiza, kugurisha kunyerera kumpera yikingira ya kaseti ya PTFE yubushyuhe bwo hejuru biterwa ahanini ningaruka ziterwa no kunanirwa kumubiri kaseti hamwe nibidukikije bikabije.

I. Impamvu Zitera Kugurisha

Impande za PTFE zifite ubushyuhe bwo hejuru zifite icyuho Mugihe cyo kubyara ubushyuhe bwinshi, imbaraga zifata kaseti zigabanuka uko ubushyuhe buzamuka. Iyo gufatira bidahagije kugirango uhangane nubushyuhe bwumuriro, impande za kaseti zizunguruka gato hanyuma zibe icyuho cya capillary, bituma uwagurishije amazi yinjira imbere.

Ingaruka yo gukuramo no kugurisha urugomero rwabacuruzi Solder ikunda kunyerera ahantu h'ubushyuhe bwo hejuru. Iyo agace karinzwe kari hejuru yubushyuhe buringaniye, umugurisha wamazi azamuka hejuru akoresheje icyuho cya kaseti muburyo busanzwe Ingaruka. Mubyongeyeho, kaseti ya PTFE ikabije cyane izakora intambwe kumpande, itera kwirundanya kwabacuruzi gukora urugomero rwabagurisha, ibyo bikarushaho kwiyongera kubagurisha.

Ubwiza bwibintu bidahuye bya kaseti ya PTFE yubushyuhe bwo hejuru Ububiko bufatika bwa kaseti ntoya ya PTFE ikunda gutemba, kwangirika no gusigara ku bushyuhe bwinshi. Ntabwo yangiza inzitizi yo gukingira gusa, ahubwo inanduza amakariso, byongera cyane ibyago byo kugurisha ibicuruzwa.

Umwanda uhumanya kaseti ya PTFE Nubwo kaseti yaba idahwitse, guturika no kumenagura amasaro yagurishijwe asigaye muri PCB ya PCB, cyangwa uduce duto duto two kugurisha twatewe na flux vaporisation mugihe cyo kugurisha ibintu, birashobora kwinjira cyangwa kurenga ahantu harinzwe kandi bigatera umwanda.

Kutamurika bidakwiye no guhindagurika mubikorwa Kunanirwa guhanagura hejuru yikingira cyangwa gukanda bidahagije mugihe cyo gufata kaseti bizasiga icyuho cyinjira mubacuruzi. Kwiyongera kwubushyuhe bwihuse mugihe cyo kugurisha byongera cyane ibicuruzwa byabacuruzi, byoroshye guca kumupaka wa kaseti ya PTFE.

Ubushuhe buhebuje bwa zahabu isahani yakajije umurego ikibazo hejuru ya zahabu isizwe na zahabu yibiza biranga ibicuruzwa byiza cyane. Iyo umugurisha amaze guhura hejuru yizahabu, ikwirakwira vuba kuruhande rwa kaseti, bikavamo intera nini cyane kuruta OSP hamwe nuburyo busanzwe bwo kugurisha ikirere gishyushye.Indwara nka pinholes ya zahabu na ruswa ya nikel bizatera ubushuhe budasanzwe bwaho kandi bikarushaho kwiyongera ku bagurisha ibicuruzwa.

II. Ibisubizo: Gahunda yo Gusaba Gahunda yo Kuzuza ubuziranenge bwa PTFE

Hitamo ibicuruzwa byujuje ubuziranenge kandi usuzume ibikorwa bya lamination Kwemeza kaseti yo mu rwego rwo hejuru ya PTFE yubushyuhe bwo hejuru yakozwe cyane cyane kubikorwa bya PCB yubushyuhe bwo hejuru, hamwe nubushyuhe bwa 250 ~ 260 ℃ kugirango wuzuze ibisabwa nta musaruro utangwa. Kwambara uturindantoki mugihe cyo gukora kugirango wirinde kwanduza amavuta.

Irinde isaro ryabacuruzi kumeneka kumeneka kugirango ukingire Adopt nkeya-igabanije kugurisha paste ya formula hanyuma uhindure ubushyuhe bwo kugabanuka. Ubushuhe buhagije bwirinda guhumeka bikabije kandi bigabanya ibyago byo kugurisha amasaro mato acamo kaseti.

Shimangira imicungire yo gucapa nibikoresho byoza ibikoresho Sukura stencil nyuma yo gucapa buri PCBs 2-3, hanyuma ukoreshe uburyo bwo guhanagura bwumye + vacuum kugirango wirinde paste yagurishijwe kumaseti ya kaseti. Kuraho buri gihe ifu yabagurisha isigaye kumashini icapa, inzira ya mount hamwe nibikoresho kugirango ukureho umwanda wa kabiri.

Igenzura ryinjira kandi ritunganijwe neza kugirango huzuzwe imbogamizi zisabwa Saba abatanga PCB gutanga ibyemezo byujuje ibyangombwa byujuje ibyangombwa kugirango babone vias zuzuye kandi birinde amasaro yihishe kugurisha kurenga kaseti ikingira. Tegura igenzura ridasubirwaho ku mbaho ​​zometseho zahabu. Iyo ibibazo bimaze kugaragara nka zahabu yoroheje na nikel yangirika, funga ibicuruzwa bifite inenge kugirango wirinde ibicuruzwa bikabije biterwa no kugurisha bidasanzwe.

Emera ubundi buryo kugirango ugabanye gushingira kaseti Niba ibicuruzwa bibyemerewe, koresha uburyo bwo kuvura bwatoranijwe, nka zahabu yohasi ku mbaho ​​gusa no gutunganya intoki za zahabu. Ibi bivanaho gukenera gukingirwa hamwe na kaseti ya PTFE kandi bikemura byimazeyo ikibazo cyabacuruzi.

Guhitamo gushyira mu gaciro, kumurika bisanzwe hamwe no kugenzura uburyo bwuzuye bwo kugenzura PTFE yubushyuhe bwo hejuru ni urufunguzo rwibanze rwo kurandura ibicuruzwa. Gutezimbere ibisobanuro birambuye birashobora kuzamura umusaruro mwinshi no kugabanya amafaranga yo gukora.

Ibikoresho bya tekinike byavuzwe haruguru bitangwa na Jiangsu Aokai Ibikoresho bishya byikoranabuhanga Co, Ltd.

Niba ukeneye ibipimo birambuye, dosiye zikoreshwa hamwe nibisubizo byabigenewe kubitambaro byubushyuhe bwo hejuru bwa PTFE, kaseti yubushyuhe bwo hejuru bwa PTFE, umukandara wa meshi wa PTFE, umukandara wimashini utagira kashe, umwenda umwe wa PTFE wuzuye umwenda, umukandara wa convoyeur wihanganira ubushyuhe bwinshi hamwe nigitambara cya fiberglass, nyamuneka twandikire:

·  Bwana Liu: +86 13705266308

Twisunga filozofiya yubucuruzi yumwuga nubunyangamugayo, kandi dutanga igisubizo kimwe gishyigikira inganda kandi tunatekereza nyuma yo kugurisha kubakiriya bisi.
