Yepamusoro-Kuita Zvishandiso zveATE uye Rodha Board Dhizaini

Nhanganyaya kune ATE PCB Zvishandiso

Kuita kwezvinhu kunokanganisa zvakananga kurongeka uye kuvimbika mune otomatiki bvunzo michina yekushandisa. Kusiyana nemabhodhi edunhu akajairwa, ATE PCB zvinhu zvinofanirwa kuchengetedza chiratidzo chekuvimbika mukati meakawanda bvunzo kutenderera uku uchishingirira kushushikana kwemechani kubva kudzokororwa probe kubata. Mamiriro emagetsi ezvishandiso izvi anotarisisa kana masaini ekumhanya-mhanya anosvika pabvunzo pasina kukanganisa, zvichiita kuti kusarudzwa kwezvinhu kuve chinhu chakakosha mukuita kwebvunzo system.

General semiconductor PCBs inoisa pamberi pemutengo wakanaka uye kuvimbika kwakajairwa, asi mabhodhi ebvunzo anoshanda pasi pemamiriro akasiyana. ATE application inoda zvinhu zvinochengetedza mhando yechiratidzo pamafrequency anopfuura 10 GHz uku ichitsigira nzira dzakaonda dzenzira dzinodiwa pakuyedzwa kwechizvino-zvino.

Zvinodikanwa Zvinokosha zveATE PCB Zvishandiso muMamiriro Ekuedza

High-Speed ​​Signal Transmission

Kutendeseka kwechiratidzo kunova kwakakosha kana zvinhu zveATE PCB zvikatakura zviratidzo zvekuyedza pahuwandu hwemagigahertz. Kusashanda kwe dielectric yakaderera (Dk) uye chinhu chinodzima zvishoma (Df) zvinodzivirira kuora kwechiratidzo pamitsetse yekutumira, zvichiita kuti zviyero zvakarurama zvisvike pamudziyo uri kuyedzwa. Kusarudzwa kwezvinhu kunokanganisa zvakananga kana kudzora kwe impedance kuchiramba kwakasimba munzira yese yechiratidzo, kunyanya mumabhodhi ekutakura anobatanidza magetsi ekuyedza kune mapurojekita eprobe.

Temperature Endurance for Burn-In Boards

Burn-in yekuyedza zvidzidzo zve semiconductor zvishandiso kune yakakwira tembiricha kwenguva yakareba, inoda ATE PCB zvinhu zvine kugadzikana kwekupisa kwekupisa. Zvishandiso zvinofanirwa kuchengetedza kurongeka kwedimensional uye zvinhu zvemagetsi patembiricha inosvika 125°C kusvika 150°C pasina delamination kana warping.

Girazi shanduko yekudziya tembiricha (Tg) zviyero pamusoro pe170 ° C inovimbisa kutsva-mukati mabhodhi anorarama mazana emafuta ekutenderera uku achichengetedza kunyoreswa pakati pemabhodhi layer. Uku kutsungirira kwekupisa kunosiyanisa bvunzo-giredhi zvinhu kubva yakajairika PCB laminates.

Mechanical Kugadzikana muMakure-Size Boards

Mabhodhi emutoro uye makadhi ekuferefeta anowanzo kudarika akajairwa PCB zviyero, aine mamwe magadzirirwo anotora 500mm kusvika 700mm. ATE PCB zvinhu zvinofanirwa kuramba warpage mukati meaya mafomati mahombe kuchengetedza chaiyo probe-to-pad kurongeka panguva yekuyedza. Coefficient of thermal expansion (CTE) inofananidzwa pakati pezvishandiso uye zvimiro zvekusimbisa inodzivirira dimensional kudhirika iyo inogona kukanganisa kuvimbika kwekusangana.

Yakajairika Yepamusoro-Kuita ATE PCB Zvishandiso

Megtron 6 uye Megtron 7 yeHigh-Frequency Applications

Megtron 6 inoshanda semuyero weindasitiri wekushandisa ATE ine ruzha rwakawanda inoda kurasikirwa kushoma kwechiratidzo. Iyi laminate ine ruzha rwakaderera ine simba rekurasa zvinhu pasi pe0.005 pa10 GHz, zvichiita kuti ive yakakodzera mabhodhi ekutakura zvinhu anobata bvunzo dzemhando yepamusoro dzemidziyo.

Megtron 7 inowedzera kugona uku nekuwedzera kwakaderera kwe dielectric constant values ​​(Dk inenge 3.3 pa 10 GHz), ichitsigira kutumira masaini mumapuratifomu ekuedza echizvarwa chinotevera anoshanda kupfuura 20 GHz frequency ranges. Zvinhu zvese izvi zvinochengetedza hunhu hwemagetsi hwakagadzikana pakuchinja kwetembiricha kunoitika panguva yekuedzwa kwekugadzira.

Ma laminate emhando yepamusoro-soro anoenderana nezvinodiwa zvePCB zveATE uko hunhu hwe dielectric hwakakodzera. Iyo laminate yemhando yepamusoro-soro inopa kugona kugadzikiswa kwakafanana neFR-4 yakajairwa uku ichiramba ichikwanisa kugadzikiswa zvakanaka pakati pema frequency netembiricha.

laminate yakasarudzika ine kurasikirwa kushoma inopa chivakwa chakazara neceramic kune zvishandiso zvinoda kugadzikana kwakanyanya mu microwave test fixtures uye RF probe cards. CTE yemhuri dze laminate dzakasarudzwa dzine kurasikirwa kushoma dzinoenderana nemhangura, zvichideredza kupisa mumaburi akaputirwa.

Polyimide uye FR-408HR yeHigh-Temperature Applications

Yepamusoro-tembiricha yekutsva-mu maapplications anovimba nepolyimide-yakavakirwa ATE PCB zvinhu zvinokwanisa kushingirira zvakanyanya kudziya nharaunda. Zvinhu izvi zvinochengetedza kutendeseka kwemaitiro pakuenderera kwekushanda tembiricha ye150 ° C kusvika 200 ° C, ine tembiricha yegirazi inodarika 250 ° C.

FR-408HR inopa mhinduro yepakati, ichipa yakawedzera kupisa kwekuita (Tg 180 ° C) kupfuura yakajairwa FR-4 kugona uku ichichengetedza kuenderana neyakajairwa PCB kugadzira maitiro. Nyaya iyi inokodzera mabhodhi ekutsva anoshanda ari pakati nepakati tembiricha ye125°C kusvika 150°C.

Panasonic R-5775(N) yeMultilayer Load Boards

Complex multilayer load board kuvaka inoda zvinhu zvine tembiricha yepamusoro yegirazi uye yakaderera Z-axis yekuwedzera maitiro. Panasonic R-5775 (N) inogadzirisa izvi zvinodiwa neTg kukosha kwe180 ° C uye inodzorwa yekuwedzera zvivakwa zvinodzivirira kuburikidza nekuputika kwebhari panguva yekupisa bhasikoro.

Iyi sisitimu yemidziyo inotsigira akaturikidzana anodarika makumi matatu akaturikidzana uku uchichengetedza kunyoresa kurongeka kwakakosha kune dense test pad arrays. Iwo akaderera CTE maitiro anovimbisa kugadzikana kwedimensional pane yakakura-fomati yekuremedza bhodhi madhizaini.

Kusarudzwa kwezvinhu neBoard Type yeATE Applications

Kusarudza yakakodzera ATE PCB zvinhu zvinoenderana nechaiyo bhodhi mabasa mukati meyedzo system. Imwe neimwe mhando yebhodhi inosangana yakasarudzika yemagetsi, yekupisa, uye mekiniki mamiriro ayo anoraira akakwana emhando yezvinhu.

Mabhodhi ekutakura zvinhu anonyanya kubatsira kubva kuMegtron 6 hunhu nekuti anofambisa masaini e-gigahertz-range pakati pemachaneli ekuyedza uye ma interface emidziyo. Makadhi eprobe anoda zvinhu zvinotsigira kugona kwekunyora mumutsara mutete (kusvika ku50μm) uye kuburikidza nekugadzirwa kwearrays dzekubatana dzakasimba.

Mabhodhi anopisirwa mukati anoshanda nguva dzose pakupisa kwakakwira, zvichiita kuti pave nekugadzirwa kwepolyimide kuti irambe yakavimbika panguva yekuratidzwa kwekupisa kwenguva refu kunotora maawa makumi mana nemasere kusvika zana nemakumi matanhatu nemasere.

Kugadzira uye Mutengo Kufunga kweATE PCB Zvishandiso

Lamination Control yeLow-Loss Cores

Kugadzira yakaderera-kurasikirwa ATE PCB zvinhu zvinoda chaiyo lamination paramita kuchengetedza zvivakwa zvemagetsi. Kutenderera kunofanirwa kuwana resin yakazara kuyerera pasina kuwandisa kwezvinhu, kunyanya kune epamberi laminates seMegtron 7 uko nhoroondo yekupisa inokanganisa dielectric performance.

Key lamination parameters dzinosanganisira:

• Kudzorwa kudziyisa mitengo -Zvishoma nezvishoma tembiricha ramps inodzivirira kushatisa resin uye kuchengetedza yakaderera Df maitiro.
• Optimized pressure profiles - Yakaenzana kudzvinyirira kugovera inovimbisa yunifomu resin kuyerera pasina fiber kuratidzwa.
• Atmosphere control -Nitrogen nharaunda lamination inoderedza oxidation mhedzisiro pakufambiswa kwechiratidzo.

Surface Pedzisa Kuenderana

Yakakwira-frequency ATE application inoda kupera kwepamusoro kunoderedza kurasikirwa kweganda uku ichitsigira yakavimbika probe kubata. Electroless nickel kunyudzwa goridhe (ENIG) inoramba iri iyo yakajairwa sarudzo yemabhodhi ekuremedza, ichipa yakanakisa planarity uye kuonana kuramba pazasi 5 miriyoni.

Sirivha yekunyudza inopa yakagadziridzwa mashandiro emagetsi panguva dzakanyanyisa asi inoda kungwarira kuchengetedza mapuroteni kudzivirira kusvibisa. Mamwe maapplication anoshandisa goridhe rakaomeswa plating panzvimbo dzekusangana kuti dzimire kupfeka kwemakanika kubva pakudzokororwa kwekuita probe.

Cost-Performance Optimization

Mari yezvinhu zveATE PCB yekushandisa inogona kudarika yakajairwa bhodhi zvinhu nezvinhu zvekatatu kusvika kashanu. Mainjiniya anofanirwa kuenzanisa mashandiro ekuita zvinopesana nezvinetswa zvebhajeti nekuchengetedza zvigadzirwa zveprimiyamu zvemasaini akakosha maseru apo vachishandisa yakajairwa FR-4 cores munzvimbo dzisiri dzakakosha stackup.

Zvivako zveHybrid zvinosanganisa akakwira-frequency epamusoro akaturikidzana neakajairwa emukati akaturikidzana anogona kudzikisa huwandu hwemitengo yezvinhu ne30 kusvika 40 muzana pasina kukanganisa bvunzo. Iyi nzira inochengetedza kutendeseka kwechiratidzo pamatanho ekunze ekufambisa paunenge uchishandisa zvinhu zvinodhura zvesimba uye ndege dzepasi.
