Kev tsim khoom loj ntawmHDIboard luam ntawv Circuit Court boards muaj ib tug series ntawm complex thiab meej txheej txheem ntws, txhua yam uas muaj ib tug tseem ceeb heev cuam tshuam rau qhov zoo ntawm cov khoom zaum kawg.
theem kev tsim khoom
Kev npaj cov ntaub ntawv: Xaiv cov khoom zoo - cov ntaub ntawv zoo yog lub hauv paus rau kev ua kom zoo ntawm HDI boards. Feem ntau siv substrates muaj xws li siab- zaus thiab cov ntaub ntawv poob qis xws li TG fr4, ROGERS, Teflon, thiab lwm yam. Cov ntaub ntawv no muaj cov khoom siv hluav taws xob zoo thiab cov khoom siv hluav taws xob zoo thiab tuaj yeem ua tau raws li cov kev xav tau ntawm HDI boards hauv ntau qhov kev thov. Nyob rau tib lub sijhawm, lwm cov ntaub ntawv xws li tooj liab ntawv ci, cov yeeb yaj kiab semi-kho, solder mask number case, thiab lwm yam yuav tsum tau npaj.
Sab hauv txheej Circuit Court ntau lawm: Hloov tooj liab ntawv nyiaj mus rau lub substrate thiab tsim cov txheej txheej hauv Circuit Court los ntawm cov txheej txheem xws li photolithography thiab etching. Nyob rau hauv cov txheej txheem no, nws yog ib qhov tsim nyog los xyuas kom meej qhov tseeb thiab zoo ntawm lub Circuit Court, tshem tawm ntau tshaj tooj liab ntawv ci, thiab ua kom lub Circuit Court kom meej thiab tsis muaj burrs. Rau ntau- txheej HDI boards, ntau txheej txheej sab hauv yuav tsum tau ua thiab sib koom ua ke los ntawm cov txheej txheem lamination.
Laminated txheej txheem (lamination): Siv lub tshuab nqus tsev kub xovxwm txheej txheem, lub rooj tsav xwm hauv Circuit Court, ib daim ntawv kho, thiab cov ntawv nyiaj sab nrauv yog laminated thiab laminated raws li kev tsim qauv. Cov txheej txheem no yuav tsum muaj kev tswj xyuas qhov kub thiab txias, siab, thiab lub sijhawm kom ntseeg tau tias qhov kev ua tau zoo ntawm cov txheej txheem rwb thaiv tsev, tsis muaj delamination lossis npuas hauv pcb, thiab txhim kho cov khoom siv dag zog. Lub laminated Circuit Court board ua ib qho tag nrho, muab lub hauv paus rau kev ua haujlwm tom ntej.
Drilling & dhau los ntawm - qhov electroplating: Laser drilling lossis siab - precision mechanical drilling yog siv los ua kom tiav micro dig muag faus qhov thiab siab - ntom ntom ntom (HDI) cov qauv. Laser drilling tuaj yeem ua tiav qhov me me thiab qhov tseeb dua, ua tau raws li qhov kev thov rau qhov me me hauv HDI boards. Tom qab drilling ua tiav, dhau los ntawm - qhov electroplating yog nqa tawm kom tso cov txheej txheem tooj liab rau ntawm lub qhov phab ntsa los ntawm cov txheej txheem tooj liab plating thiab electroplating, kom ntseeg tau tias cov tooj liab tuab tuab, txhim kho kev ntseeg tau, thiab ua kom muaj kev sib txuas hluav taws xob sib txawv.
txheej ntawm circuits.
Txheej txheej Circuit Court fabrication & deg kev kho mob: Circuit Court yog fabricated nyob rau sab nrauv tooj liab ntawv ci siv photolithography, etching, thiab lwm yam txheej txheem. Tswj impedance kom raug (hauv ± 5%) kom haum rau siab -ceev teeb liab kis tau tus mob (xws li 5G, millimeter yoj, thiab lwm yam). Nyob rau hauv cov nqe lus ntawm kev kho deg, peb muaj ntau yam txheej txheem kev xaiv xws li immersion kub, ENIG, OSP, ENEPIG, thiab lwm yam. Cov txheej txheem no tuaj yeem txhim kho vuam kev ntseeg tau thiab oxidation tsis kam, ua kom ruaj khov kev ua tau zoo ntawm lub rooj tsav xwm hauv Circuit Court thaum sib dhos thiab siv tom ntej.
Kev sim theem
AOI tsis siv neeg kho qhov muag tshuaj ntsuam xyuas: Siv cov khoom siv tsis siv neeg AOI tag nrho, cov tsos ntawm lub rooj tsav xwm Circuit Court raug tshuaj xyuas tag nrho. Los ntawm kev sib piv nrog cov duab preset standard, xyuas seb puas muaj luv luv circuits, qhib circuits, tooj liab slag, corrosion thiab lwm yam teeb meem nyob rau hauv Circuit Court kom ntseeg tau tias cov tsos yog tiav thiab tsis muaj kev puas tsuaj. AOI kuaj tau sai thiab raug kuaj pom feem ntau cov tsos mob, txhim kho kev tsim khoom thiab cov khoom zoo.
Kev sim impedance & siab- kev ntsuas kev ua haujlwm zaus: Siv TDR kom raug kuaj qhov sib txawv ntawm 50 Ω, 90 Ω, thiab 100 Ω kom tau raws li qhov xav tau ntawm siab - cov cim ceev thiab RF microwave circuits. Rau siab -PCBs zaus, kev sim VNA kuj tseem yuav ua kom ntseeg tau tias lawv cov yam ntxwv poob qis thiab ua kom zoo thiab ruaj khov ntawm cov teeb liab thaum sib kis.
Short circuit detection&X-Ray analysis: siv txoj kev xws li flying pin testing and ICT online circuit testing kom paub meej tias txhua txoj hauv kev hluav taws xob zoo li qub thiab xyuas seb puas muaj qhov qhib lossis luv Circuit Court. Los ntawm kev siv X-ray perspective soj ntsuam, cov teeb meem sab hauv xws li BGA solder pads, laminated bonding zoo, thiab uniformity ntawm filling yuav raug soj ntsuam, thiab tej zaum yuav zoo txaus ntshai yuav raug txheeb xyuas raws sij hawm.
Kev ntsuam xyuas kev ntxhov siab & kev ntseeg siab: Ua kev sim kev ntseeg siab xws li TCT thiab IST los simulate qhov kub thiab txias tsis zoo, rov ua dua, thiab lwm yam xwm txheej uas cov rooj sib tham hauv Circuit Court yuav ntsib thaum siv tiag tiag, kom ntseeg tau tias pcb tuaj yeem tiv taus cov kev ntxhov siab ib puag ncig yam tsis muaj kev tawg lossis delamination, thiab ua kom muaj kev ntseeg siab thiab ruaj khov ntawm cov khoom sib txawv.
Kev Tswjhwm Zoo ntawm HDI Board pcb Batch Manufacturing
Kev tswj hwm nruj nruj yog tus yuam sij rau kev ua kom ruaj khov thiab txhim khu kev qha khoom zoo hauv cov txheej txheem tsim khoom loj ntawm HDI cov laug cam thiab cov ntawv luam tawm.
Raw khoom zoo tswj
Tswj kom zoo los ntawm qhov chaw thiab ua nruj soj ntsuam ntawm cov khoom siv raw khoom. Ntsuam xyuas cov tuab, tooj liab ntawv nplaum, kev ua haujlwm hluav taws xob thiab lwm yam ntsuas ntawm tooj liab-clad laminates kom ntseeg tau tias lawv ua tau raws li cov qauv tsim. Kev tshuaj xyuas zoo kuj tseem ua rau lwm cov ntaub ntawv xws li solder mask number case thiab semi cured films. Tsuas yog cov ntaub ntawv tsim nyog tuaj yeem nkag mus rau hauv cov txheej txheem tsim khoom kom tsis txhob muaj cov khoom tsis xws luag los ntawm cov khoom siv raw khoom tsis zoo.
Kev soj ntsuam zoo ntawm cov txheej txheem ntau lawm
Tsim kom muaj kev saib xyuas zoo tshaj plaws thaum lub sijhawm tsim khoom. Kev saib xyuas lub sijhawm tiag tiag thiab sau cov cim tseem ceeb rau txhua tus txheej txheem, xws li lub sijhawm etching thiab qhov kub thiab txias hauv cov txheej txheem etching, thiab kub, siab, thiab lub sijhawm hauv txheej txheem laminating. Los ntawm tus kheej tsim los ntawm MES system (Manufacturing Execution System), kev tswj cov txheej txheem nruj, cov ntaub ntawv - tsav tswj, thiab kev tswj qhov muag tau siv los xyuas kom sai thiab kho cov xwm txheej txawv txav hauv cov txheej txheem tsim khoom, kom ntseeg tau tias txhua yam khoom ua tau raws li cov qauv zoo.
