FR4 epoxy galasi CHIKWANGWANI gulu laminating ndondomeko

Masitepe akuluakulu a FR4 epoxy glass fiber board akuphatikizapo Kutentha, kukanikiza, kuchiritsa, kuziziritsa, kupukuta, ndi zina zotero.

1. Preheating stage: Ikani bolodi la epoxy mu makina osindikizira otentha ndikuwotchera kwa mphindi 30 pa kutentha kwa pafupifupi 120 ° C, kuti epoxy resin ndi zowonjezera zowonjezera ziphatikizidwe bwino, ndipo zowonongeka zimasefukira. Sitepe iyi ndi yovuta kwambiri. Ngati nthawiyo ndi yochepa kwambiri ndipo kutentha sikukwanira, n’zosavuta kutulutsa thovu, ngati kutentha kuli kwakukulu komanso nthawi yayitali kwambiri, chopanda kanthu chidzatuluka.

2. Gawo lopangira makina osindikizira otentha: Panthawi imeneyi, kutentha, nthawi, ndi kupanikizika zidzakhala ndi zotsatira zachindunji pa chinthu chomaliza, ndipo zinthuzi ziyenera kukhala zikusintha motsatira zipangizo zosiyanasiyana. Mwachitsanzo, pa nsalu ya epoxy phenolic laminated, kutentha kumayikidwa pafupifupi 170 ° C, ndipo ngati nsalu yagalasi ya epoxy silikoni, kutentha kumayikidwa pafupifupi 200 ° C. Ngati bolodi ndi woonda, kuchepetsa kutentha kukanikiza kutentha.

3. Kuziziritsa ndi kugwetsa: Mukakanikiza, ikani bolodi la epoxy m’madzi ozizira kuti muzizire, nthawi ili pakati pa theka la ola ndi ola limodzi. Panthawi imeneyi, chidwi chiyenera kuperekedwa pa kusintha kwa kupsinjika kwa mkati. Kuwonjeza kochuluka kwa matenthedwe ndi kupindika kumapangitsa kuti bolodi la laminated likhale lopindika ndi kupunduka.

4. Pambuyo pa chithandizo: Njira iyi ndikupangitsa kuti ntchito ya epoxy board ikhale yopambana. Mwachitsanzo, kuyika bolodi lopangidwa mu uvuni kuti muzitha kutentha kumatha kuthetsa zotsalira zamkati.
