Radar y'imodoka ya Rogers Microwave RF PCB
PCB ifite umurongo wo hejuru wa radar y'imodoka ya Millimeter Wave
5G n'ingendo zigendanwa ni umusaruro w'ubufatanye bukomeye bw'inganda z'imodoka n'ikoranabuhanga rishya rigezweho nk'itumanaho, ubwenge bw'ubukorano n'ikoranabuhanga rigezweho rya IoT. Ni byo byerekezo by'ingenzi by'iterambere ry'ikoranabuhanga n'ikoranabuhanga ku rwego rw'isi mu bijyanye n'imodoka n'ubwikorezi. Imodoka yigenga ifite ikoranabuhanga rya 5G ishobora kugera ku gutwara neza no kugira uburambe bwo gutwara neza. Kohereza amajwi ya 5G vuba bizaha sisitemu y'imodoka umwanya uhagije wo gutanga ibitekerezo no gutunganya, bityo bikarinda umutekano w'imodoka kandi bigatanga uburambe bwo gutwara neza.
Ikoreshwa ry'ingenzi mu gutwara ibintu mu buryo bwikora ni sensor za radar za millimeter wave, zikoresha cyane cyane ibikoresho nka RO3003G2TM, RO3003TM, RO4830TM, CLTE-MWTM, nibindi. Zikoreshwa cyane muri radar ya millimeter wave ya 77GHz kandi zifite dielectric constant ihamye cyane na ultra-low dissipation factor (factor ya dissipation ya 0.001 ikunze kugeragezwa kuri 10 GHz). Muri icyo gihe, imiterere idafite fibre y'ikirahure igabanya cyane ihindagurika rya dielectric constant yo mu gace ka millimeter wave frequency band, Gukuraho ingaruka za fiberglass z'ikimenyetso byongera cyane ubwiza bw'itsinda rya sensor ya radar.
Bitewe n’iterambere ry’ibikoresho bya radar muri 79 GHz (77-81 GHz), umurambararo wabyo wagutse w’amajwi ushobora kunoza ubushobozi bwa sensor za radar, kongera inguni zo gushakisha, ndetse no kugera ku ishusho ya 4D.
Rogers PCB yo gukoresha sensor ya radar ya milimetero (reba ishusho ya 1 na 2 kugira ngo umenye byinshi)
Imbonerahamwe y'ibipimo bya (Rogers)RO3003™ PCB ifite frequency yo hejuru
(Rogers) RO3003™ Substrates zikoresha frequency nyinshi ni ibikoresho bya PTFE byuzuyemo ibumba, bikoreshwa muri PCB mu mikoroonde y'ubucuruzi na porogaramu za RF. Imiterere yihariye ituma ibikoresho bigumana ubusugire kandi bikuraho impinduka mu buryo bwa dielectric ku bikoresho bya PTFE bisanzwe ku bushyuhe bw'icyumba.
Rogers RO3003™ Substrates zifite frequency yo hejuru ziracyafite imiterere ihamye ya dielectric (Dk: 0.00+/- 0.04) na dissipation factor (Df: 0.0010 kuri 10GHz) ku bushyuhe butandukanye n'imirongo ngenderwaho. Birakwiriye cyane gukoreshwa nka milimetero y'imodoka (77 GHz), sisitemu zigezweho zo gufasha gutwara (ADAS) n'ibikorwa remezo bya 5G by'insinga (milimetero y'insinga).
Substrate ya RO3003™ ifite ubushobozi bwo guhagarara neza mu buryo bwa mekanike, bigatuma abashushanya bakoresha ibikoresho bifite imiterere itandukanye ya dielectric mu buryo bw'icyiciro kimwe mu gihe bashushanya circuits zifite urwego rumwe rudahindagurika cyangwa ngo habeho ibibazo byo kwizerwa. Coefficient yo kwaguka k'ubushyuhe bwa substrate ya RO3003™ mu cyerekezo cya X/Y ni 17/16 (ppm/℃). Iki giciro kingana n'coefficient yo kwaguka k'ubushyuhe bwa umuringa, bityo agaciro gasanzwe ko gucika (guteka nyuma yo gucika) k'ibikoresho ni munsi ya 0.5mils/inch, bigaragaza ubushobozi bwo guhagarara neza. CTE mu cyerekezo cya Z ni 25 (ppm/℃), kandi ndetse no mu bushyuhe bukabije, iki gikoresho gishobora kwemeza ko electroplated ikomeza guhagarara binyuze mu myobo.
Ishusho ya 1: Ihindagurika ry'ubushyuhe bw'ingufu zikoresha amashanyarazi za RO3003 na RO3035 laminates riterwa n'ubushyuhe
Nkuko bigaragara ku ishusho iri hejuru, ibipimo bya dielectric bya laminates za RO3003 na RO3035 bigaragaza ko bihamye neza bitewe n'ubushyuhe. Nta mpinduka mu bipimo bya dielectric ku bushyuhe bw'icyumba nk'ibipimo bya fibre ya PTFE.
Ishusho ya 2: Igipimo cyo gukwirakwiza RO3003 na RO3035.
Ishusho iri hejuru igaragaza uko ibintu bikwirakwiza ibintu mu miyoboro ya RO3003 na RO3035 bikwirakwira. Uburyo bwo gupima bwa RO3003-RO3035: IPC-TM-65025.5.5 Imiterere y'igerageza: 10 GHz 23 °C.
Porogaramu
Ikoreshwa rya substrate ifite frequency nyinshi (reba ishusho ya 3-1 kugira ngo umenye byinshi)
Ibirango bisanzwe by’ibice bipima inshuro nyinshi: ARLON substrate ifite frequency nyinshi, TACONIC high-frequency substrate, ROGERS high-frequency substrate, Shengyi, Taiguang, Taiyao, Fushide, Wangling n’ibindi bicuruzwa byinshi. Isosiyete ikora: Rogers, Taconic, F4B, TP-2, FR-4 n’ibindi bice bipima inshuro nyinshi, byihutishije isuzuma mu masaha 24.
Rogers, nk'umucuruzi ukomeye ku isi utanga ibikoresho byihariye, afite isoko rirenga 50% ku isi yose n'uburambe bw'imyaka 20 mu nganda mu bijyanye na antene ya RF yo kuri sitasiyo.
Ibikoresho bya Rogers bifite umurongo ngenderwaho munini bigizwe n'uruhererekane 3000, uruhererekane 4000, uruhererekane 5000, nibindi.
RICHPCBA yibanda ku gukora PCB za RF za mikoroonde zifite ibyiciro 2-68 n'ibindi bicuruzwa, hamwe n'ibikoresho bya Rogers bifite intera iri hejuru biboneka, bitumizwa mu ipaki yabyo y'umwimerere hamwe n'ubwoko bwose bw'ibikoresho. Dutanga serivisi zo gupima, gutunganya no gutunganya PCB za Rogers.
Imiterere y'ibikoresho bya PCB bifite imikorere ihanitse: bikoreshwa cyane mu bikoresho by'itumanaho, mu nganda zigenzura, mu mazu agezweho, mu bikoresho by'amashanyarazi byihariye, mu mashini z'ubuvuzi n'ahandi.
Radar y'imodoka; Antene ya GPS; Sisitemu y'itumanaho igendanwa: amplifier y'amashanyarazi na antene; Antene iriho itumanaho ridafite insinga; Satellite yo kohereza amakuru mu buryo butaziguye; Sisitemu y'insinga yo guhuza amakuru; Igisomwa cya metero kare n'inyuma y'amashanyarazi, nibindi;
