Rigid-Flex Akadhindwa Mabhodhi: Matanho Matatu Ekuchenesa Mukati meMakomba

Mune rigid-flex yakadhindwa mapuranga, nekuda kwekusagadzikana kwakashata kwekuputira pamadziro egomba (pure rabha firimu uye bonding sheet), zviri nyore kuita kuti jira riparadzane kubva pamadziro egomba kana richiiswa mukupisa kwekupisa. , inodawo kuzorora kweanenge 20 μm, kuitira kuti mhete yemhangura yemukati uye electroplated mhangura iri mune yakavimbika-matatu-point kuonana, iyo inovandudza zvakanyanya kupisa kwekuvhunduka kwegomba resimbi. Iyo inotevera Capel ichataura nezvayo zvakadzama kwauri. Matanho matatu ekuchenesa gomba mushure mekuboora rigid-flex board.

Ruzivo rwekuchenesa mukati megomba mushure mekuboora rigid flex circuits:

Sezvo polyimide isingamiri kune alkali yakasimba, nyore yakasimba alkaline potassium permanganate desmear haina kukodzera kuchinjika uye kuomarara-flex akadhindwa mabhodhi. Kazhinji, tsvina yekuchera pabhodhi yakapfava uye yakaoma inofanira kucheneswa neplasma yekuchenesa maitiro, iyo yakakamurwa kuita matanho matatu:

(1) Mushure mekunge chivharo chemidziyo chasvika pane imwe dhigirii yevacuum, yakakwira-kuchena nitrogen uye yakakwirira-kuchena okisijeni inobayiwa mairi muchiyero, basa guru nderekuchenesa madziro egomba, preheat bhodhi rakadhindwa, uye kugadzira iyo polymer zvinhu. ita chimwe chiitiko, chinobatsira Chinotevera kugadzirisa. Kazhinji, i80 degrees Celsius uye nguva yacho maminetsi gumi.

(2) CF4, O2 neNz vanoita neresin segasi rekutanga kuzadzisa chinangwa chekubvisa uye kudzoreredza kumashure, kazhinji pa85 degrees Celsius uye kwemaminitsi makumi matatu nemashanu.

(3) O2 inoshandiswa segasi rekutanga kubvisa zvakasara kana "guruva" rakaumbwa mumatanho maviri ekutanga ekurapa; chenesa gomba rusvingo.

Asi zvakakosha kucherechedza kuti kana plasma inoshandiswa kubvisa tsvina yekuchera mumakomba emapuranga e-multi-layer anoshanduka uye akaoma-anoshanduka akadhindwa, kukurumidza kwekugadzirisa kwezvinhu zvakasiyana-siyana kwakasiyana, uye kurongeka kubva kuhombe kusvika kudiki ndeiyi: acrylic film. , epoxy resin , polyimide, fiberglass uye mhangura. Misoro yefiber yegirazi yakabudikira nemhete dzemhangura zvinoonekwa zvakajeka pamadziro egomba kubva pamaikorosikopu.

Kuti ive nechokwadi chekuti electroless copper plating solution inokwanisa kubata zvizere madziro egomba, kuitira kuti mhangura yemhangura irege kuburitsa voids uye voids, zvakasara zveplasma reaction, iyo inobudikira girazi fiber uye polyimide firimu pamadziro gomba inofanirwa kuve. kubviswa. Nzira yekurapa inosanganisira makemikari mechanical uye mechanical nzira kana kusanganiswa kwezviviri. Nzira yemakemikari ndeyekunyorovesa bhodhi rakadhindwa neammonium hydrogen fluoride solution, uye wozoshandisa ionic surfactant (KOH solution) kugadzirisa kubhadharisa kwegomba remadziro.

Mechanical nzira dzinosanganisira high-pressure wet sandblasting uye high-pressure yekugeza mvura. Iko kusanganiswa kwemakemikari uye mechanical nzira kune zvakanakisisa. Mushumo wemetallographic unoratidza kuti mamiriro emadziro ane simbi yegomba mushure mekusvibiswa kweplasma inogutsa.

Izvo zviri pamusoro apa matanho matatu ekuchenesa mukati megomba mushure mekuchera mabhodhi akaoma-flex akadhindwa zvakanyatsorongwa neCapel. Capel yakatarisa pane yakaomesesa yakadhindwa yedunhu bhodhi, yakapfava bhodhi, yakaoma bhodhi uye SMT gungano kwemakore gumi nemashanu, uye yakaunganidza hupfumi hweruzivo rwehunyanzvi muindasitiri yebhodhi redunhu. Ndinovimba kugovera uku kunobatsira kune wese. Kana iwe uine mimwe mimwe mibvunzo yebhodhi redunhu, ndapota bvunza yedu Capel makeup indasitiri tekinoroji timu zvakananga kuti ipe nyanzvi yehunyanzvi rutsigiro rweprojekiti yako.
