Iyo PCB Yakaoma Firimu Inotamba Basa Rakakosha Mukusimudzira PCB Kuvimbika

Chii chinonzi PCB Dry Film?

Firimu rakaoma chinhu chinoshandiswa kugadzira maPCB kugadzira circuit pattern. Rinoiswa pamusoro pe laminate yakaputirwa nemhangura uye rinozoiswa kuchiedza cheUV kuburikidza ne mask yefirimu ine circuit pattern. Mwenje weUV unorapa nzvimbo dzakaratidzwa dzefirimu rakaoma, woriomesa uye wogadzira layer inodzivirira pamusoro pema traces emhangura. Mushure mekuratidzwa, nzvimbo dzisina kuratidzwa dzefirimu rakaoma dzinobviswa, zvichisiya circuit pattern pamusoro pemhangura. Firimu rakaoma rinowanzoshandiswa mukugadzira maPCB nekuda kwe resolution yaro yepamusoro, kunamira zvakanaka kumhangura, uye nyore kugadzirisa. Ngatinzwisisei maitiro ekugadzira maPCB pattern pamwe chete:

Masking Makomba muDy Firimu

Kana uchivhara maburi mune yakaoma firimu maitiro, akati wandei zvinhu zvinofanirwa kutariswa kuti ive nechokwadi chekubudirira mhedzisiro:

• Deredza kupisa kwefirimu uye kudzvinyirira kuti udzivise kukanganisa.
• Vandudza gomba madziro roughness uye tip kuitira nani adhesion.
• Wedzera simba rekuratidzwa kuti uwedzere kutevedza kwefirimu.
• Deredza kusimba kwekusimudzira kwekuita kwakapfava.
• Dzivisa nguva refu pakati pekushandiswa kwefirimu uye kuratidzwa kudzivirira kupararira kwefirimu.
• Ita shuwa kuti firimu rakaoma rinoshandiswa pasina kusimba zvakanyanya kudzivirira deformation.

Kupinda mune Dry Film Electroplating

Kupinza kunoitika apo mhinduro ye electroplating inopinda pakati pefirimu yakaoma uye foil yemhangura, zvichiratidza kusanamatira kusina kunaka. Dambudziko iri rinogona kukonzerwa ne:

• Tembiricha yefirimu isiriyo, ingave yakakwira zvakanyanya kana yakaderera, inokanganisa kunamatira kwefirimu.
• Kudzvanywa kwemufirimu kwakashata, kunotungamira kune nzvimbo dzisina kuenzana kana mapundu anokanganisa kunamatira.
• Simba rekuratidzira risina kukwana, zvichikonzera kusakwana kwepolymerization uye kunamatira kusina simba.
• Kudzora kwakaringana panguva idzi maitiro kwakakosha kudzivirira kukanganisa uye kuve nechokwadi chepamusoro-mhando PCB musangano.

Surface Blisting muPCB Kugadzira

Surface blistering chirema chakajairika mukugadzirwa kwePCB, kunokonzerwa nezvinhu zvakasiyana:

• Substrate kugadzirisa nyaya, senge kusabatana kwakashata pakati pefoiri yemhangura uye kemikari mhangura.
• Kusvibiswa kubva kumachining maitiro kana zvimwe zvinwiwa, zvinotungamira kumarara emafuta.
• Yakawandisa kudzvanywa panguva yemhangura brashi plating, zvichikonzera deformation uye kunotevera mablistering.
• Matambudziko ekugeza mvura, kusanganisira kusvibiswa kwemuchinjiko uye kusabatwa zvakanaka kwebhodhi repamusoro.
• Micro etching nyaya mu pretreatment, zvichitungamira kune base material leak uye blistering.
• Kushanda kwakasimba kwemhangura yekunaya kwemvura, zvichikonzera kusanamatira kwekunamatira.
• Oxidation yebhodhi pamusoro panguva yekugadzirwa.
• Kusashanda zvakanaka kwemhangura, zvichikonzera kuputika nekuda kwenzira dzisina kunaka kana kusakwana kwekutonga.
• Kusakwana kwekugeza mvura mushure mekuvandudzwa kana kusvibiswa kweguruva mumusangano.
• Kutadza kutsiva matangi ekunhonga, zvinotungamira kuhutsanana uye kushata kwepamusoro.
• Organic kusvibiswa, kunyanya kusvibiswa kwemafuta, mumatangi e electroplating.
• Kuchaja mabhodhi ePCB achipinda mumatangi, kunyanya ayo ane kuvhiringika kwemhepo, anofanirwa kuchengetedzwa nemazvo kudzivirira kukanganisa.

Nekunzwisisa matambudziko aya nekuita kudzora kwakaringana, vagadziri vePCB vanogona kuwedzera kunaka uye kuvimbika kwezvigadzirwa zvavo, vachizadzisa zvinodiwa zvemagetsi emazuva ano.

Shandura PCB yako kugadzira neyedu yekucheka-kumucheto PCB yakaoma firimu tekinoroji! Yedu photosensitive firimu inovimbisa kurongeka uye kushanda nesimba mukufambisa edunhu mapatani pamatanda emhangura, ichivimbisa emhando yepamusoro, yakaoma maPCB. Taura zvakanaka kumaitiro echinyakare uye kumbundikira ramangwana rekugadzirwa kwePCB nePCB yedu yakaoma firimu mhinduro!

Kana chinodiwa ichi chichikanganisa kuwanikwa kana kuburitswa kwezvigadzirwa, chienzanise nemaitiro ekusimbisa mhando yePCB uye ongororo yekudzora impedance usati watumira mafaira ekupedzisira kuti aongororwe.
