Kuongororwa kweiyo laminating maitiro eFR4 epoxy girazi fiber board

FR4 epoxy girazi fiber board inogona kupa yakazara kutamba kune yayo mechaniki zvivakwa pasi pekushisa kwepakati; pasi pemamiriro ekushisa kwepamusoro, inogona kupa kutamba kwakakwana kune zvayo zvemagetsi. Naizvozvo, nekuda kwehunhu uhwu, epoxy board yakanyatso kukodzera kune yakakwirira-insulation zvimiro zvikamu mumagetsi nemagetsi minda. Iyo ine yakakwira mechanic simba uye kuramba kuparara kwevoltage kupfuura iyo yenyika standard 3240 board.

FR4 epoxy girazi fiber bhodhi matanho makuru anosanganisira kudziyisa, kudzvanya, kurapa, kutonhora, kudhiza uye zvichingodaro.

Nezve iyo lamination maitiro eFR4 epoxy girazi fiber bhodhi

1. Pre-heating stage: Isai bhodhi epoxy muchitsiko chinopisa 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 iyo nguva ipfupi uye tembiricha isina kukwana, zviri nyore kuburitsa matema, kana tembiricha yakanyanya kukwirira uye iyo nguva iri refu, isina chinhu ichatsvedza.

2. Hot press molding stage: Muchikamu chino, tembiricha, nguva, uye kudzvanywa zvichave nemhedzisiro yakananga pachigadzirwa chekupedzisira, uye zvinhu izvi zvinofanirwa kugara zvichichinja zvichienderana nechinhu. Semuenzaniso, munyaya ye epoxy phenolic laminated jira, tembiricha inoiswa paanenge 170 ° C, uye kana iri epoxy silicone girazi jira, tembiricha inoiswa panenge 200 ° C. Kana bhodhi iri mutete, dzikisa kupisa kwekushisa.

3. Kutonhodza nekudzikisa: Mushure mekudzvanya, isa epoxy board mumvura inotonhora kuti itonhodze pasi, nguva iri pakati pehafu yeawa neawa imwe. Munguva iyi, kutarisisa kunofanirwa kubhadharwa kuchinjiso chemukati kushungurudzika. Kuwedzera kupisa kwekupisa uye kukanda kunokonzeresa kuti laminated board iite kutenderera nekuremara.

Post-kurapwa: Danho iri nderekuita kuti kuita kwe epoxy board kuve kwepamusoro. Semuenzaniso, kuisa bhodhi rakagadzirwa muchoto kuitira kupisa kupisa kunogona kubvisa mukati mekutambudzika kusara.
