Nigute Wokwirinda Ibisigarira Bifata & Amaraso Yivanze ya PTFE Ifata Ubushyuhe Bwinshi Mugihe Kurinda Urutoki rwa PCB Zahabu muri SMT

Jiangsu Aokai Ibikoresho bishya, ukora umwuga wo gukora PTFE yubushyuhe bwo hejuru, atanga ubuyobozi bwumwuga. Iyo kaseti ya PTFE yubushyuhe bwo hejuru ikoreshwa mukurinda intoki za zahabu PCB mugihe cyo guterana kwa SMT, ibisigara bifata neza (kubitsa bifatanye bisigara ku ntoki za zahabu nyuma yo gukuramo kaseti) hamwe no kuva amaraso yometseho (gufatira byoroheje no gutemba hejuru yubushyuhe bwinshi, byanduza ahantu hatakingiwe cyangwa hejuru ya PCB) nyuma yo kugurisha ibintu bidahuye cyane cyane no gutoranya kaseti idahuye. Hasi ni urutonde rwibisubizo:

I. Impamvu Imizi Isesengura ryibisigisigi & Amaraso

1. Ibisigisigi bya Adhesive  Bibaho mugihe ifatizo ihuye nikibazo cyo kunanirwa hamwe (gutanyaguza imbere murwego rwo gufatisha) cyangwa kunanirwa kwimura intera (gutandukanya ibimera biva munsi ya substrate hanyuma bikomeka ku ntoki za zahabu). Imbarutso zisanzwe zirimo ubushyuhe budahagije bwa kaseti, ibifata imyaka, cyangwa igihe cyo gukuramo nabi.

2. Amaraso ya Adhesive  Amababi ya afashe agabanuka cyane munsi yubushyuhe bwo hejuru, bigatuma amazi yiyongera cyane. Munsi yigitutu cya lamination nigikorwa cya capillary, ibifatika byuzura kaseti. Ubusanzwe ibyo biterwa no gufunga umubyimba mwinshi cyane, kuzamuka kwubushyuhe bwihuse, cyangwa kutagira ubushyuhe bukabije bwumuriro wibiti ubwabyo.

II. Guhitamo Ibishushanyo Byiza - Igisubizo Cyibanze

Kaseti isanzwe ya PTFE ntishobora kuzuza ibisabwa bikabije bya SMT. Ibicuruzwa byabugenewe byihariye byo kurinda urutoki rwa SMT bigomba guhitamo, hamwe nibyingenzi bihabwa imikorere ya sisitemu ifatika:

 

· Urwego rwo Kurwanya Ubushyuhe : Kurwanya ubushyuhe bwigihe gito ≥ 300 ° C, ubushyuhe bwa serivisi bukomeza ≥ 260 ° C, burenze kure ubushyuhe bwo hejuru bwo kugurisha ibicuruzwa bitagira isukari (245-250 ° C).

· Uburebure bwa Layeri : Ubunini buri hejuru ntiburinganiza gukomera. Hitamo kaseti zifite uburebure bwa 0.08–0.13mm, zirimo ibice bito ariko bifatanye cyane kugirango bigabanye cyane ibyago byo kuva amaraso.

· Icyemezo cyo Kurwanya Amaraso & Ibisigisigi byubusa : Saba raporo yikizamini cyo kurwanya amaraso n’ibisigisigi byahariwe kurinda urutoki rwa zahabu SMT kurinda ibicuruzwa, kandi ukore ibizamini by’itanura hamwe n’icyitegererezo.

III. Intambwe Zitandatu Zigenzura Igenzura

1. Mbere yo Kumurika: Gusukura Ubuso & Mbere yo Kuvura

· Kwangirika kwuzuye: Intoki za zahabu hamwe nubuso bwa PCB bigomba kuba bitarimo ibyuya, ibyanduza amavuta nibisigara bya flux. Ihanagure hamwe nigitambara kitarimo linti cyinjijwe muri etanol ya anhydrous cyangwa alcool ya isopropyl (IPA), hanyuma wumye rwose.

· Substrate yumye: Menya neza ko PCBs idafite ubushuhe mbere yo gukoresha kaseti.

2. Kumurika: Zeru Zeru & Kwimuka Byuzuye

· Ntukarambure kaseti: Substrate ya PTFE ifite ihindagurika ryiza. Kurambura mugihe cyo kumurika bitera guhangayika imbere bitera kugabanuka munsi yubushyuhe bwinshi, bikaviramo gushwanyagurika, ibisigara cyangwa kuva amaraso. Shyira kaseti isanzwe hejuru yintoki za zahabu hanyuma ukande byoroheje kugirango ubanze ufate.

· Gukuraho umwuka wuzuye: Koresha uruzitiro rwabigenewe cyangwa scraper ikomeye kugirango usunike buhoro buhoro icyerekezo kimwe kuva hagati kugera kumpande zombi kugirango uhuze neza. Menya neza ko impande zose zifatika zidafite umuyaga mwinshi; ibituba byaguka munsi yubushyuhe no kuzamura impande za kaseti, bigatera gufatira hejuru.

· Guhuza neza: Guhuza kaseti ya kaseti ihinduranya urutoki rwa zahabu cyangwa winjizemo gato kuri 0.2–0.5mm (niba byemewe). Ntuzigere upfundika amakariso cyangwa vias, kuko capillary siphonage izashushanya ibishishwa byashongeshejwe hanze.

3. Kugaragaza Kugurisha: Hindura Umwirondoro w'Ubushyuhe

· Kurikiza byimazeyo ubushyuhe bwa kaseti: Gupima ubushyuhe bwukuri bwibibaho kugirango wizere ubushyuhe bwo hejuru hamwe nigihe cyose ubushyuhe buzaguma murwego rwo kwihanganira kaseti.

· Gushyushya ubwitonzi bworoheje: Komeza igipimo cyo gushyushya gahoro (<2 ° C / s) mbere yo kugera ahantu horoheje (150 ° C - 200 ° C). Ubushuhe butunguranye butunguranye bworoshe kwifata no gusenyuka kwijimye, biganisha kumaraso menshi.

4. Igihe cyo gukuramo igihe: Ubukonje bukonje butanga ibisubizo byiza

· Gira ubukonje bwuzuye mubyumba: Nyuma yo kugurisha, tegereza kugeza ubushyuhe bwa PCB bugabanutse munsi ya 50 ° C (ubushyuhe bwibidukikije) mbere yo gukuramo kaseti. Ibifatika bikomeza byoroshye kandi bifatanye cyane ku bushyuhe bwinshi; ku gahato gishyushye byoroshye byoroshye gutandukanya ibice hamwe na kole isigaye.

· Tekinike yo gukuramo: Kuramo buhoro buhoro kuri 180 ° inguni n'imbaraga imwe. Ntugakwega niba uhuye nikibazo.

5. Gucunga inzira: Igenzura Ubuzima bwa Shelf & Koresha Amagare

· Saba kandi utunganyirize ako kanya: PCB hamwe na kaseti ya laminated igomba kwinjira mu itanura ryihuse. Irinde kubika igihe kirekire (amasaha arenga 24) mumahugurwa kugirango wirinde kwinjiza amazi no kwirundanya umukungugu.

· Gukoresha inshuro imwe gusa kumatanura: SMT kaseti yubushyuhe bwo hejuru ni ikintu gishobora gukoreshwa. Nubwo kaseti igaragara neza nyuma yo gutanura itanura rimwe, ibifatika byahujwe no gusaza; icyiciro cya kabiri cyo gushyushya bizatera rwose ibisigisigi bifatika cyangwa kunanirwa. Kubice bibiri byubatswe PCBs, usimbuze kaseti nshya-mbere yo gutunganya uruhande rwa kabiri nyuma yo gutambuka kwambere.

6. Kunanirwa gukemura ibibazo byihutirwa & Kwemeza

· Kujugunya utubuto duto duto: Halt umusaruro uhita uboneka ibisigazwa. Ihanagura witonze hamwe na IPA-yuzuye imyenda idafite lint; ohereza imbaho ​​zo gukora isuku yumwuga mubihe bikomeye. Ntuzigere usiba ibikoresho bikomeye.

· Kwemeza ibyangombwa bishya byemewe: Kora umusaruro wuzuye wikigereranyo hamwe na PCBs 1: 1. Nyuma yo gutanura itanura, kura kaseti hanyuma urebe aho urutoki rwa zahabu ruri munsi ya 40-50x ya magnifier kugirango wemeze ibisigisigi bya zeru hamwe na zeru zuzuye.

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

Niba wifuza kubona ibisobanuro birambuye, ibintu bisabwa hamwe nibisubizo byabigenewe kubicuruzwa byacu byuzuye birimo imyenda ya PTFE yubushyuhe bwo hejuru, kaseti ya PTFE yubushyuhe bwo hejuru cyane, umukandara wa meshi wo mu bushyuhe bwo hejuru, umukandara w’ubushyuhe utagira umuyaga, umwenda wa PTFE, umwenda umwe w’ubushyuhe hamwe n’igitambaro cya fiberglass, nyamuneka twandikire ukoresheje amakuru akurikira:
