Maitiro Ekugadzira PCB eFR408HR uye Kuvimbika kweMultilayer

FR408HR multilayer reliability is created by the complete fabrication route. Material identity, inner-layer movement, copper balance, resin demand, lamination, drilling, hole-wall preparation, copper deposition, controlled-depth operations, inspection and change control all interact. A high-performance laminate cannot compensate for a poorly defined stackup or an uncontrolled interconnect process. For FR408HR multilayer fabrication and assembly, stackup approval, lamination controls and reflow exposure should be reviewed together with the project’s reliability requirements.

Gwaro iri rinotevera matanho ekugadzira anokanganisa kuvimbika kweFR408HR multilayer, kubva pakugadzirira zvinhu uye kugadzirisa mukati memukati kusvika pakunamirwa, kuboorwa, kuputirwa, kuongororwa, uye kudzora kugadzirwa zvakare.

Usati waburitsa, simbisa kuti zvinhu zvakagadziriswa, zvinodiwa zvekusapindira, kugadzwa kwezvinhu, chimiro chemaburi, uye hurongwa hwekuongorora zvese zvinoenderana nenzira yaunoda kugadzira.

Nei FR408HR Ichida Kugadziriswa kwePCB Kunodzorwa

FR408HR inogona kugadziriswa mukati menzira dzakagadzirwa dzePCB dzakawanda, asi nzira yacho inofanira kugadzirwa zvichienderana nekuvakwa chaiko. Maitiro ekupisa, kuyerera kweresin, nhoroondo yehunyoro, kufamba kwehukuru, kugoverwa kwemhangura, magadzirirwo emaburi uye kupisa kwakawanda zvinosarudza kana bhodhi rapera rakavimbika.

Maitiro Ezvinhu Ane Chekuita Nekugadzira

Maitiro ekugadzira haanyanyi kukanganiswa ne "high-performance FR-4" pane maitiro chaiwo ezvinhu. Isola inotsanangura FR408HR senzira inoenderana neFR-4, asi gwara rayo rekugadzirisa rinotaurawo kuti mazano evatengesi ndiwo mavambo ayo mugadziri wega wega anofanira kugadzirisa nekusimbisa mumidziyo yake nemidziyo yebhodhi.

Ronga Chivako Usati Wasarudza Nzira

Kupatsanura uku kunobatsira kudzivirira kuomarara kusingakoshi. Bhodhi remazuva ano rine zvidimbu gumi harifanirwe kumanikidzwa kupinda munzira yeHDI nekuti fekitori inoripa, nepo dhizaini yeBGA yakakora haifanirwe kubatwa senzvimbo yemazuva ese yekungoderedza mutengo wakataurwa.

Kugadzirira Zvinhu Zvinouya uye Kugadzira

Kugadzirwa hakufanirwe kutanga kusvika magwaro aburitswa, kuvakwa kwezvinhu, mamiriro ekuchengetera, kuzivikanwa kwenzvimbo, kuunganidzwa kwezvinhu, mhangura, data rekuboorera, zvinodiwa zvekupindira uye hurongwa hwekuongorora zvabvumirana. Zvikanganiso padanho iri zvinova zvakaoma kugadzirisa mushure mekuiswa kwelamination.

Kuburitswa Kweinjiniya Zvinhu Zvisati Zvachekwa

Maitiro acho anotanga pasati patanga kugadzirwa kwepaneru yekutanga. CAM neinjiniya yemaitiro vanofanirwa kubatanidza ruzivo rwevatengi nezvivakwa zveFR408HR zviripo uye nzira yakakodzera yefekitori.

Gadzirisa chikumbiro chezvinhu

Dhirowa rinofanira kuratidza Isola FR408HR laminate uye prepreg, kana kutsanangura zvakaenzana zvakatenderwa. Magwaro ekugadzira akaburitswa anofanirawo kutaura kana chinodiwa ichi chichishanda kune yega yega dielectric layer, kana kuvakwa kwehybrid kuchibvumidzwa, uye kana magwaro ezvinhu achidikanwa pakutumirwa.

Chinja dhizaini yakagadzirwa kuita chivakwa chinovakwa

Ukobvu hwe dielectric hunobva muchishandiso cheEDA hahuzivi zvakananga core ne prepreg zvichatengwa. Mugadziri anosarudza magirazi aripo, zviri mukati me resin, huremu hwemhangura, uye zvivakwa zve nominal, obva afanotaura ukobvu hwakadzvanywa mushure mekutarisa pattern yemhangura uye kudiwa kwe resin. Magadzirirwo e controlled-impedance haafanire kuenderera mberi kusvika tafura yekugadzira stackup ne impedance yaenderana.

Tsanangura makuponi neuchapupu pakuronga kwepaneru

Makuponi eImpedance, makuponi echikamu chidiki, makuponi eplating, sampuro dzekugona kusundirwa, uye maumbirwo ekuyedza evatengi anoshandisa nzvimbo yepaneli. Anofanira kurongwa usati waashandisa. Kuawedzera mushure mekugadzirisa mapaneli kunogona kuchinja goho, mutengo, kana kuunzwa.

Gadza hwaro hwekuchinja-kutonga

Kugadziriswa kwakabudiswa kunofanirwa kuratidza seti yedata reinjiniya rakatenderwa, zvinhu, kuunganidzwa, uye hurongwa hwekuongorora. Chero shanduko ipi zvayo inotevera pakuvaka, foil yemhangura, kupedzisa pamusoro, kana nzira yekushanda inofanira kuongororwa zvichienderana nekutanga ikoko.

Kusimbiswa kweZvinhu zveFR408HR, Kuchengetedza uye Kutevedza

Kudzora kunopinda kunoita kuti dhizaini chaiyo isavakwe nezvinhu zvisiri izvo. Kusimbisa kunogona kusanganisira label yemutengesi, mhuri yezvinhu, ukobvu hwepakati, huremu hwemhangura, dhizaini yegirazi reprepreg, zviri mukati me resin, mamiriro epepa kana roll, mamiriro ekuchengetera, uye zvinodiwa nevatengi kuti vatore chitupa.

Kuongororwa kweLaminate
