I-KB-6165 PCB Laminate: Imininingwane, Izicelo kanye Nomhlahlandlela Wokuklama

1. Isingeniso ku-KB-6165 Laminate

I-KB-6165 laminate iyinto ephezulu ye-Tg FR-4 eyenzelwe izinhlelo zokusebenza ze-PCB ezixinene kakhulu nezinezingqimba eziningi ezidinga ukuhambisana kokuhlanganiswa okungenalo i-lead. Lo mhlahlandlela uhlola amapharamitha abalulekile kagesi, okushisa, kanye nowomshini anquma ukuthi i-KB-6165 iyafanelana yini nezidingo zakho zomklamo.

Sikhava izakhiwo ze-dielectric, imikhawulo yokuthembeka kwe-thermal, ukucatshangelwa kokukhiqiza, nezindawo zokuhlola zokuqinisekisa ukuze sisize onjiniyela, abaklami, namaqembu okuthenga enze izinqumo zezinto ezibonakalayo ezinolwazi.

2. KB-6165 Amapharamitha angukhiye ngokubuka nje

Ithebula elilandelayo lifingqa imininingwane ebalulekile evela kudatha ye-KB-6165 . Sebenzisa lokhu ukuhlola okusheshayo ngaphambi kokucwila ekuhlaziyeni okuningiliziwe.

2.1 Izicelo Ezinconyiwe

Amabhodi e-multilayer (izendlalelo ezi-4–16), okokusebenza kwezokuxhumana, izilawuli zezimboni, izinto zikagesi ezithengwayo ezidinga ukuhlanganiswa okungakhokhelwa, namadizayini asebenza ngaphansi kuka-3 GHz lapho ukusebenza kwe-dielectric kwe-FR-4 kwamukelekile.

2.2 Sebenzisa Ngokuqaphela noma Ukugwema

Iziphetho zangaphambili ze-Millimeter-wave RF (>10 GHz), izinhlelo zokusebenza ezidinga ukulahlekelwa okuphansi kakhulu (i-Df <0.005), ukuhamba ngebhayisikili okushisayo okudlulele okungaphezu kokuchayeka okuqhubekayo okungu-260°C, noma imiklamo lapho ubuqotho besignali budinga kulawulwa ukubekezelelwa kuka-Dkt kumaza aphezulu.

3. Kungani Lawa Mapharamitha e-KB-6165 Abalulekile

Ukuqonda ukuthi incazelo ngayinye isho ukuthini ngomklamo wakho we-PCB kusiza ukuvala igebe phakathi kwamanani eshidi ledatha kanye nezinqumo zokusebenza zangempela.

3.1 Ukusebenza kukagesi: Dk kanye no-Df

I-dielectric constant (Dk = 4.5 ejwayelekile @ 1 MHz) ithinta ngokuqondile izibalo ze-impedance kanye ne-trace geometry. Ngemiklamo evimbelayo okulawulwayo, sebenzisa inani lika-Dkt elishiwo lomkhiqizi kunokuqagela okujwayelekile kwe-FR-4 (ngokuvamile 4.2–4.8). I-tangent yokulahlekelwa (i-Df = 0.018 ejwayelekile) ithonya ukuncishiswa kwesignali-okwamukelekayo kuma-interfaces edijithali angaphansi kwe-GHz kanye nesivinini esimaphakathi, kodwa onjiniyela abasebenza kuzixhumanisi ze-SerDes zamagigabhithi amaningi kufanele baqinisekise ukusebenza kwemvamisa yabo yokusebenza, njengoba i-Df ivame ukwanda ngemvamisa.

3.2 Ukuthembeka Kokushisa: Ukuhambelana kwe-Tg, Td, nokugeleza kabusha

I-KB-6165's Tg yokungu-153°C iqinisekisa ukuzinza kwe-dimensional ngokusebenzisa amaphrofayili okugeleza angenamthofu ajwayelekile (isiqongo ~245–260°C). I-Td ka-335°C ihlinzeka ngemajini ngaphambi kokubola kwezinto ezibonakalayo. I-T-260 (amaminithi angu-50 ajwayelekile) kanye ne-T-288 (amaminithi angu-23 ajwayelekile) abonisa ukuthi i-laminate imelana isikhathi eside kangakanani namazinga okushisa aphakeme ngaphandle kwe-delamination—amamethrikhi abalulekile emijikelezweni yokugeleza kabusha eminingi, izimo zokuphinda zisebenze, kanye ne-wave soldering. Amadizayini adinga uhambo oluphindiwe olushisayo noma ukusebenza okunwetshiwe kwethempelesha ephezulu kuyazuza kule mikhawulo evulekile.

3.3 Izakhiwo zikaMechanical kanye ne-Z-axis CTE

I-Z-axis CTE (55 ppm/°C evamile ngaphansi kwe-Tg, 3.1% isamba sokunwetshwa) ithinta ngokwethembeka kuzitaki zezendlalelo eziningi. Ukunwetshwa kwe-Z-axis ephansi kunciphisa ingcindezi emigodini egqinsiwe phakathi nokuhamba ngebhayisikili okushisayo, kunciphisa ukuqhekeka kwemiphongolo kanye nezingozi zokuphakamisa amaphedi. Amanani wamandla aguquguqukayo (560 N/mm² warp, 430 N/mm² fill) abonisa ukuqina okuhle kokuphathwa nokuhlanganisa. Mayelana ne-high-aspect-ratio vias (ukujula-kuya-kububanzi >8:1), ukuziphatha kwe-CTE elawulwayo kwe-KB-6165 kuba okubaluleke kakhulu.

3.4 I-Surface Finish Compatibility

I-KB-6165 iyahambisana nokuqedwa okujwayelekile kwendawo okuhlanganisa i-ENIG, OSP, i-immersion tin, ne-HASL. I-ENIG ihlinzeka ngokuhleleka okuhle kakhulu kwe-BGA ye-fine-pitch kanye nokuthengiswa okungaguquki ngaphezu kwesitoreji esinwetshiwe. I-OSP inikeza ukusebenza kahle kwezindleko zemiklamo enezidingo ezimfishane zempilo yeshelufu. Amandla ekhasi angu-1.35 N/mm (1 oz copper @ 125°C) abonisa ukunamathela kwethusi okuthembekile kuzo zonke lezi zinqubo zokuqeda.

3.5 Ukusimama Kwendawo Ezungezile kanye Nezitifiketi

Ngesilinganiso sokuvutha kwe-UL94 V-0 nokuhambisana ne-RoHS, i-KB-6165 ihlangabezana nezimfuneko eziyisisekelo zokulawula zezinhlelo zokusebenza eziningi zezohwebo nezimboni. Ukumunca umswakama ophansi (0.30% ojwayelekile) kanye nokumelana ne-CAF amahora angu-1000 kuwenza ulungele izindawo ezinomswakama. Izinhlelo zokusebenza zezimoto noma zezokwelapha zingase zidinge ukuhlolwa okwengeziwe kokufaneleka okungaphezu kokuthotshelwa kwe-IPC-4101E/21 okujwayelekile.
