Nekukurumidza kukurumidza kweiyo indasitiri yemagetsi, PCB wiring iri kuramba ichinyatsojeka. Vazhinji vagadziri vePCB vanoshandisa yakaoma firimu kupedzisa graphic kuchinjisa, uye kushandiswa kweyakaoma firimu kuri kuwedzera kuve kwakakurumbira. Nekudaro, mukuita kwekutevera-kutengesa sevhisi, ini ndakasangana nevatengi vazhinji vakaita zvikanganiso zvakawanda pavanoshandisa yakaoma firimu.

Kutanga, pakaoma mabhuti masiki masiki anoonekwa

Vatengi vazhinji vanofunga, mushure megomba rakatyoka, rinofanira kuwedzera tembiricha yefirimu uye kumanikidza, uye kusimudzira simba ravo rinosunga, zvirokwazvo rudzi urwu rwemaonero haruna kunaka, nekuti mushure mekupisa tembiricha uye kumanikidza, ngura inodzivirira rukoko rweyakawandisa solvent volatilization, ita iyo yakaoma firimu yakapfava yakaonda uye iri panjodzi yekupaza nepaburi painenge ichivandudza, isu tinogara tichida kuramba takaoma firimu kuomarara, saka, mushure megomba rakatyoka, tinogona kuzviita kubva pane anotevera mapoinzi ekuvandudza:

1, kuderedza tembiricha yefirimu uye kumanikidza

2, kunatsiridza kuchera drape pamberi

3, kuvandudza kusvibiswa kwesimba

4, deredza kuwedzera kumanikidza

5, iyo yekupaka nguva mushure mefirimu haigone kuve yakarebesa, kuti isatungamira kuchikamu chekona cheiyo semi-fluid firimu pasi pechiito chekumanikidza diffusion kutetepa

6, usatambanudze iyo yakaoma firimu yakanyanyisa mukuita kwefirimu

Maviri, yakaoma firimu rairo inoitika kupinda mukati

Chikonzero chekupinda mukati ndechekuti iyo yakaoma firimu uye yemhangura-yakapfeka foil haina kusungwa zvakasungwa, izvo zvinodzamisa iyo yekumhara mhinduro uye inowedzera iyo “yakaipa chikamu” chikamu chekupfeka. Kupinda mukati kunowanikwa mune vazhinji vePBB vagadziri nekuda kwezvikonzero zvinotevera:

1. Yakakwirira kana yakaderera yekuratidzira simba

Pasi pechiedza che ultraviolet, iyo photoinitiator iyo inopinza mwenje wesimba yakaora kuita yakasununguka radical kutanga monomer kune photopolymerization reaction, ichiumba iyo molekyuru yemuviri isingasviki mukudzora alkali mhinduro. Kana kuratidzwa kwacho kusakwana, nekuda kwekusakwana kwemapolimerization, mukugadzira, firimu kuzvimba kunova nyoro, zvichikonzera mitsara isina kujeka uye kunyangwe furuji inodonha, zvichikonzera kusanganiswa kwefirimu nemhangura. Kana kuratidzwa kwacho kuri kwakanyanyisa, kunokonzeresa kuumbika, uye zvakare kuchaburitsa kuruka uye kupfekenura muchikamu chekupaka, ichigadzira yekupinda. Saka zvakakosha kudzora simba rekuburitsa.

2. Iyo tembiricha tembiricha yakakwira kana yakaderera

Kana iyo tembiricha tembiricha yakanyanya kuderera, nekuda kweiyo ngura yekudzivirira firimu haigone kunyorovera zvakakwana uye kuyerera kwakaringana, zvichikonzera kusabatana kwakasimba pakati peyakaoma firimu nemhangura yakapfeka laminate pamusoro; Kana iyo tembiricha yakanyanya kukwirira nekuda kwekukurumidza volatilization ye solvent uye zvimwe zvinhu zvisina kugadzikana mumushonga uye matubvu, uye iyo yakaoma firimu inova inopwanya, ichiumba warping peel painosanganisa magetsi magetsi, zvichikonzera kupinda mukati.

3. Iko kumanikidza kwefirimu kwakakwirira kana kuderera

Kana kumanikidzwa kwefirimu kwakanyanya kuderera, kunogona kukonzera kusakwana kwemafirimu pamusoro kana mukaha pakati pefirimu yakaoma nendiro yemhangura uye kusasangana nezvinodiwa zvekusunga simba; Kana kumanikidzwa kwefirimu kwakanyanya, izvo zvinogadziriswa uye zvisina kugadzikana zvezvinhu zvinodzivirira zvinogona kuvhiringidza, zvichikonzera firimu rakaoma, rinozove rakamonyoroka mushure mekuvhunduka kwemagetsi.
