Nzira yekugadzirisa sei dambudziko re Pcb bhodhi mhangura yakapfeka laminate

Heano mamwe eanowanzoitika PCB redunhu bhodhi matambudziko uye maitiro ekuasimbisa. Ukangosangana nematambudziko PCB laminate, unofanira kufunga kuwedzera kune PCB laminate zvinhu nokurondedzerwa. Izvi zvinotevera zvinotsanangura nzira yekugadzirisa dambudziko rePCB redunhu bhodhi copper clad laminate?

PCB redunhu bhodhi mhangura yakapfeka laminate dambudziko rimwe. Kuti ndikwanise kuronda nekuwana

Hazvibviri kugadzira chero nhamba yePCB redunhu mabhodhi pasina kusangana nemamwe matambudziko, ayo anonyanya kuverengerwa kune zvinhu zvePCB copper clad laminate. Kana matambudziko emhando akaitika mune chaiyo yekugadzira maitiro, zvinoita sekunge kazhinji nekuti iyo PCB substrate zvinhu inova chikonzero chedambudziko. Kunyangwe yakanyatso kunyorwa uye yakanyatso shandiswa PCB laminate tekinoroji yekumisikidza haitauri zvinhu zvekuyedzwa zvinofanirwa kuitwa kuti uone kuti PCB laminate ndiyo honzeri yematambudziko ekugadzira. Heano mamwe eanowanzosangana nePCB laminate matambudziko uye maitiro ekuaziva.

Ukangosangana nematambudziko PCB laminate, unofanira kufunga kuwedzera kune PCB laminate zvinhu nokurondedzerwa. Kazhinji, kana iyi tekinoroji yehunyanzvi ikasazadziswa, inokonzeresa shanduko yemhando yepamusoro uye zvozotungamira mukuraswa kwechigadzirwa. Kazhinji, matambudziko emidziyo anobva mukushandurwa kwemhando yePCB laminates anoitika mune zvigadzirwa zvinogadzirwa nevagadziri vachishandisa mabheti akasiyana ezvigadzirwa kana kushandisa akasiyana mitoro yekutsikirira. Vashoma vashandisi vane marekodhi akakwana kuti vakwanise kusiyanisa chaiwo mitoro yekutsikirira kana mabheti ezvigadzirwa panzvimbo yekugadzira. Nekuda kweizvozvo, zvinowanzoitika kuti maPCB anoramba achigadzirwa uye akaiswa nezvikamu, uye warps inoramba ichigadzirwa mune solder tank, iyo inoparadza yakawanda yebasa uye inodhura zvikamu. Kana iyo batch nhamba yekurodha zvinhu inogona kuwanikwa nekukasira, iyo PCB laminate inogadzira inogona kuonesa iyo batch nhamba yeresin, iyo batch nhamba yefoiri yemhangura, uye kutenderera kwekurapa. Mune mamwe mazwi, kana mushandisi asingakwanisi kupa kuenderera nehurongwa hwekutonga kwePCB laminate mugadziri, izvi zvichaita kuti mushandisi pachake atambure kurasikirwa kwenguva refu. Izvi zvinotevera zvinounza zvakajairika nyaya dzine chekuita ne substrate zvinhu muPCB redunhu bhodhi kugadzira maitiro.

PCB redunhu bhodhi mhangura akapfeka laminate dambudziko maviri. Dambudziko repamusoro

Zviratidzo: kutadza kudhinda kunamatira, kushomeka kweplating, zvimwe zvikamu hazvigone kuchinjika, uye zvimwe zvikamu hazvigone kutengeswa.

Nzira dziripo dzekuongorora: dzinowanzo shandiswa kugadzira mitsetse yemvura inooneka pamusoro pebhodhi kuti iongororwe nekuona:

chikonzero chinogona:

Nekuda kweiyo yakanyanya kuomarara uye yakatsetseka yepasi yakagadzirwa neyakaburitswa firimu, iyo isina kuvharwa mhangura yepamusoro inopenya zvakanyanya.

Kazhinji padivi risina kuvharwa relaminate, mugadziri we laminate haabvisi mumiririri wekusunungura.

Mapini ari mufoiri yemhangura anoita kuti resin iyerere kunze uye iungane pamusoro pefoiri yemhangura. Izvi zvinowanzoitika pamapuranga emhangura iyo yakaonda kupfuura iyo 3/4 ounce uremu hunotsanangurwa.

Iyo inogadzira foil yemhangura inopfeka pamusoro pefoiri yemhangura nehuwandu hwakawanda hwema antioxidants.

Mugadziri welaminate akachinja resin system, kubvisa mutete, kana nzira yekukwesha.

Nekuda kwekushanda zvisina kunaka, kune akawanda mafingerprints kana girizi mavara.

Dip nemafuta einjini panguva yekubaya, kuvhara kana kuchera.

Mhinduro dzinogoneka:

Usati waita chero shanduko mukugadzira laminate, shandira pamwe nemugadziri welaminate uye tsanangura zvinhu zvekuedza zvemushandisi.

Zvinokurudzirwa kuti vanogadzira laminate vashandise machira-akafanana nemafirimu kana zvimwe zvinhu zvekuburitsa.

Bata mugadziri welaminate kuti aongorore batch yega yega yemhangura foil isina kukodzera; bvunza mhinduro yakakurudzirwa yekubvisa resin.

Bvunza mugadziri we laminate nzira yekubvisa. Changtong anokurudzira kushandisa hydrochloric acid, inoteverwa nekukwesha kwemuchina kuibvisa.

Bata mugadziri welaminate uye shandisa michina kana makemikari ekubvisa nzira.

Dzidzisa vashandi mune zvese maitiro ekupfeka magirovhosi kubata mhangura yakapfeka laminates. Tsvaga kana iyo laminate inotumirwa nepedhi yakakodzera kana kutakurwa muhomwe, uye padhi ine yakaderera sulfur content, uye bhegi rekurongedza harina tsvina. Chenjerera kuona kuti hapana arikuibata kana uchishandisa silicone-ine detergent Copper foil.

Degresa ese laminates usati waputira kana maitiro ekufambisa maitiro.
