FR4 epoxy girazi faibha bhodhi laminating maitiro

Matanho makuru eFR4 epoxy glass fiber board anosanganisira kudziyisa, kudzvanya, kurapa, kutonhodza, kudhonzesa, etc. Iyo lamination process inosanganisira mana matanho:

1. Preheating stage: Isai epoxy board mumuchina unopisa uye upise iyo kwemaminitsi makumi matatu pakupisa kweanenge 30 ° C, kuitira kuti epoxy resin uye zvinhu zvekusimbisa zvibatanidzwe zvakakwana, uye zvinoputika zvakare zvinoputika. Danho iri rakakosha zvikuru. Kana nguva yacho ipfupi uye tembiricha isina kukwana, zviri nyore kugadzira mabhubhu, kana tembiricha yakanyanyisa uye nguva yakarebesa, iyo isina chinhu inotsvedza.

2. Kupisa-kuumba nhanho yekugadzira: Padanho rino, tembiricha, nguva, uye kudzvanywa zvichave nemhedzisiro yakananga pachigadzirwa chekupedzisira, uye zvinhu izvi zvinofanirwa kugara zvichichinja zvichienderana neyakasiyana zvinhu. Semuenzaniso, munyaya ye epoxy phenolic laminated jira, tembiricha inoiswa panenge 170 ° C, uye kana iri epoxy silicone girazi jira, tembiricha inoiswa panenge 200 ° C. Kana bhodhi iri mutete, dzikisa kupisa kwekushisa.

3. Kutonhora nekudzikisa: Mushure mekudzvanya, isa epoxy board mumvura inotonhora kuti itonhore, nguva iri pakati pehafu yeawa neawa imwe. Munguva iyi, kutarisa kunofanira kubhadharwa kune kuchinja kwekunetseka kwemukati. Kuwedzera kupisa kwekuwedzera uye kukanda kunokonzeresa kuti laminated board iende uye kuremara.

4. Mushure mekurapwa: Danho iri nderekuita kuti kushanda kwe epoxy board kuve kwepamusoro. Semuenzaniso, kuisa bhodhi rakagadzirwa muchoto kuitira kupisa kupisa kunogona kubvisa mukati mekutambudzika kusara.
