Maitiro ekugadzirisa dambudziko remhangura yakapfeka laminate ye PCB

Heano mamwe akajairika PCB pabhodhi matambudziko uye maitiro ekuasimbisa. Kana dambudziko rePCB laminate rasangana, rinofanirwa kutariswa kuti riwedzere kune iyo PCB Laminate tsananguro. How kugadzirisa dambudziko mhangura akapfeka laminate pamusoro pcb?

Izvo hazvigoneke kugadzira chero huwandu hwePCB pasina kusangana nemamwe matambudziko, ayo anonyanya kukonzerwa nezvinhu zvePCB mhangura-yakapfeka laminate. Kana matambudziko emhando yepamusoro akaitika mune chaiyo yekugadzira maitiro, zvinoita sekunge pcb substrate zvinhu zvinowanzo kukonzera dambudziko. Kunyangwe yakanyatso nyorwa uye yaitwa tekinoroji yakatarwa yePCB laminates haitsanangure zvinhu zvekuyedza izvo zvinofanirwa kuitwa kuti vaone kuti pcb laminates ndiyo inokonzeresa matambudziko ekugadzira maitiro. Heano mamwe eakajairika PCB Laminate matambudziko uye maitiro ekuasimbisa.

Kana dambudziko rePCB laminate rasangana, rinofanirwa kutariswa kuti riwedzere kune iyo PCB Laminate tsananguro. Kazhinji, kana hunyanzvi hwedudziro uhu husina kupfumiswa, zvinokonzeresa shanduko yemhando yepamusoro uye inotungamira kuchinhu chinobvarura. Kazhinji, dambudziko rezvinhu rinokonzerwa nekushandurwa kwePCB Laminate mhando inoitika mune zvigadzirwa zvinogadzirwa nemabatch akasiyana ezvigadzirwa kana akasiyana ekudzvanya mitoro. Vashoma vashandisi vane zvakakwana zvinyorwa zvekusiyanisa yakatarwa yekutsimbirira mutoro kana zvinhu batch panzvimbo yekugadzirisa saiti. Saka zvinowanzoitika kuti pcb inogara ichiburitswa uye kuiswa pamwe nezvikamu, uye warpage inoramba ichigadzirwa mune iyo solder groove, iyo inopambadza yakawanda yebasa uye inodhura zvinhu. Kana iyo yekurodha batch nhamba ikawanikwa ipapo ipapo, iyo PCB Laminate inogadzira inogona kutarisa iyo batch nhamba yeresin, mhangura foil, kurapa kutenderera, nezvimwe. , mushandisi pachawo anotambura kurasikirwa kwenguva yakareba. Izvi zvinotevera zvinotsanangura matambudziko akaenzana ane chekuita ne substrate zvinhu mukugadzirwa kwePCB.

Zviratidzo.

Inogona kuitika nzira dzekuongorora: kutariswa kwekutarisa kunowanzoitwa nekuumba inooneka mamaki emvura pane iyo ndiro pamusoro.

Zvimwe zvinokonzera:

Nekuda kwenzvimbo yakanyanyisa uye yakatetepa inokonzerwa nefirimu iri kupwanya, iyo isina kuvharwa mhangura yepamusoro inopenya.

Kazhinji, iyo inogadzira laminate haibvise iyo yekuburitsa mumiriri pane isina kuvharwa divi re laminate.

Pinholes mumhangura foil inokonzera resin kuyerera ichibuda uye inoungana pamusoro pemhangura foil, iyo inowanzoitika pamhangura foil yakatetepa kupfuura 3/4 oz uremu.

Vagadziri vemhangura vanoshandisa yakawandisa antioxidants kumusoro kwemhangura foil.

Vagadziri veLaminate vakachinja masystem, kuburitsa machira, kana nzira dzekutsvaira.

Nekuda kwekushanda zvisina kufanira, kune akawanda mafinger prints kana mafuta stain.

Oiri yakasvibiswa panguva yekurova, kuvhara kana kuchera mashandiro.

Mhinduro dzinogoneka:

Shandira pamwe nemugadziri we laminate uye tsanangura zvinhu zvekuyedza zvemushandisi chero shanduko dzisati dzaitwa mukugadzirwa kwe laminate.

Zvinokurudzirwa kuti vagadziri vemarara vanoshandisa machira kunge mafirimu kana zvimwe zvekuburitsa.

Bata mugadziri we laminate kuti aongorore batch yega yemhangura foil iyo inotadza kupasa kuongororwa; Kumbira mhinduro kuti ubvise iyo inokurudzirwa resin.

Kumbira iyo inogadzira laminate nzira yekubvisa. Inowanzo kukurudzirwa kushandisa hydrochloric acid, uye wozoibvisa nekugadzira nekukwesha.

Bata mugadziri we laminate kuti ushandise nzira dzekumisikidza kana kemikari.

Dzidzisa vese vashandi vemaitiro kupfeka magirovhosi uye tora mhangura dzakapfeka laminates. Ita shuwa kana iyo laminate yakanyatso kuvezwa kana kurongedzwa muhombodo panguva yekufambisa, uye sarufa yezviri mupepa rakapetwa ishoma, uye bhegi rekurongedza harina tsvina. Teerera kuti uve nechokwadi chekuti hapana anonongedzera iyo foil foil kana uchishandisa sipo ine silicone.
