a) Sake yin amfani da Chip na gani na kyamara mara lahani

Mahimman Ciwo: Masu tsabtace tsaka-tsaki ba za su iya cire abubuwan da aka warkar da zafin UV akan kwakwalwan kwamfuta ba; na'urori masu lahani an goge su gaba ɗaya, suna ɓarna abubuwan haɓaka masu ƙima.

• Magani: Tsarin alkaline na PL31 yana narkar da adhesives masu taurin kai a cikin 10min; bayan cirewa, kwakwalwan kwamfuta suna riƙe da watsa haske (gamuwa da ƙa'idodin gani na gaba ɗaya).

• Ƙimar: Yana ba da damar sake amfani da guntuwar gani a maimakon cikakken gogewa, yana tallafawa rage farashin sake aiki.

b) Sake aiki na bangaren Semiconductor

Mahimman Ciwo: Haɗin epoxy mai taurin kai akan ɓangarorin ɓangarorin semiconductor suna tilasta cikakken gogewa; masu tsabtace alkaline masu ƙarfi suna haɗarin lalata da'irorin guntu.

• Magani: pH mai sarrafawa na PL31 (11 ± 1) yana rushe shaidu ba tare da lalata fakitin jan karfe ba ko abubuwan siliki (mai dacewa da ka'idodin lantarki na gabaɗaya).

• Ƙimar: Abubuwan da aka ceto sun cika ka'idojin sake amfani, rage sharar kayan abu.

c) Daidaitaccen PCB Part farfadowa da na'ura

Abubuwan Ciwo: Abubuwan PCB masu daraja (misali, na'urori masu auna firikwensin) akan alluna marasa lahani an goge su; masu tsaftar tsaka tsaki sun kasa cire kayan adhesives masu zafi.

• Magani: PL31 da 30kHz ultrasonic tsaftacewa yana kawar da shaidu a cikin 8min; babu lahani ga PCB solder gidajen abinci.

• Ƙimar: Yana dawo da sassan sake amfani da su, daidaitawa tare da maƙasudin masana'antu masu dorewa.

Shiri

  1. Tsarma PL31 bisa ga m kauri:

•   Abubuwan da aka warkar da zafin UV masu nauyi: 1: 1 zuwa 1: 5 (PL31: ruwa DI), motsawa 30s har sai uniform.

•   Haɓakawa mai haske: 1:10 zuwa 1:20 (PL31: DI ruwa).

  2. Preheat ultrasonic mai tsabta zuwa 50-60 ℃; tabbatar da mitar (28-40kHz) don guje wa lalata kayan aiki.

Aiki

• Ultrasonic (Rework Lines): Submerge aka gyara a diluted PL31; gudanar da duban dan tayi 8-12min. Don ɗaure mai kauri, ƙara 2-3mins (sa idanu don gujewa wuce gona da iri).

• Manual (Ƙananan Batches): Yi amfani da zane mai laushi don amfani da diluted PL31; bari mu zauna 5-8min; a hankali kwasfa shaidu; kurkura da ruwan DI.

Bayan Jiyya

1. Kurkura abubuwan 2-3x tare da ruwan DI (30s kowanne) don cire ragowar PL31.

2. Dry: 60-70 ℃ tanda (5min) ko busasshen iska (minti 30) - guje wa yanayin zafi da ke lalata kwakwalwan kwamfuta.

3. Dubawa: Ayyukan ɓangarorin gwaji (misali, watsawar gani, juriya na lantarki) kowace ƙa'idodin masana'anta na gabaɗaya.

FAQ:

Q1 : Yaushe ya kamata mu yi amfani da PL31 maimakon tsaka tsaki masu tsabta?

A1 : PL31 an yi niyya ne don mannen da aka warkar da zafin UV masu taurin kai waɗanda masu tsabtace tsaka tsaki ba za su iya narke ba-misali, lokacin sake yin amfani da kwakwalwan kwamfuta mara kyau ko sassan semiconductor. Magani ne da aka yi niyya, ba maye gurbin tsabtace tsaka-tsaki na yau da kullun ba.

Q2 : Shin PL31 zai lalata suturar guntu na gani?

A2 : A'a. Ya wuce gwaje-gwajen nutsewa na sa'o'i 48 tare da kwakwalwan kwakwalwan kwamfuta masu rufi na AR (gama da ka'idojin gani na yau da kullun), yana nuna 0% peeling ko asarar watsawa - mafi aminci fiye da madadin alkaline mai ƙarfi.

Q3 : Shin PL31 ya dace da layin sake yin aiki mai girma a kudu maso gabashin Asiya?

A3 : iya. Daidaitawar sa tare da masu tsabtace ultrasonic na 28-40kHz (misali a cikin masana'antu na yanki) da madaidaitan masana'antu RoHS yarda suna goyan bayan samar da fitarwa zuwa fitarwa. Masu kera na gida sun yi amfani da shi don rage dogaro ga cikar abubuwan da ba su da lahani.

Q4 : Za a iya diluted PL31 har yanzu kiyaye bangaren ayyuka?

A4 : iya. Ko da a 1: 20 dilution, yana kula da 97.8% m kau da inganci da kuma ≥99.5% kayan aikin riƙewa (kowace ma'aunin lantarki na gaba ɗaya), daidaita farashi da aiki.

Q5 : Shin PL31 yana buƙatar ajiya na musamman don kula da tasiri?

A5 : Adana ba a buɗe ba a 15-30 ℃ (bushe, babu hasken rana kai tsaye) na watanni 12. Bayan buɗewa, rufe sosai kuma amfani a cikin watanni 3-babu tasiri akan pH ko aiki lokacin adanawa da kyau.
