Nei Sarudza ITEQ IT-180A YePCB Dhizaini Yako
Target Zvishandiso
IT-180A inokodzera magadzirirwo anoda kusimba kwekupisa uye kugadzikana kwezvikamu: maPCB ane layer yakawanda (8+ layers), maBGA uye maHDI akapfava, mabhodhi emhangura anorema (3oz+), maECU emotokari (akayerwa injini), matelecom backplanes, uye masisitimu edata/storage server. Hunhu hwayo hweUV hunovimbisawo kuti inoenderana neAOI uye masisitimu ekuona nzvimbo.
Thermal Performance Value
Iyo 175 ° C Tg uye yakaderera Z-CTE inoderedza interlayer kusagadzikana panguva yekutungamirira-isina reflow (peak 260 ° C) uye rework cycles. Iine T260 inodarika maminetsi makumi matanhatu, IT-180A inoshingirira kufamba kwakawanda kwekupisa pasina delamination-yakakosha pakuteedzana lamination inovaka uko mukati memukati unowana kudzokororwa kupisa.
Kuvimbika Kwemagetsi
A Dk ye ~4.1 pa 10GHz uye Df ye ~ 0.016 chinzvimbo IT-180A sepakati-frequency inokwanisa zvinhu. Kunyange isina kuitirwa millimeter-wave RF kumberi-kunopera, inodarika yakajairwa FR-4 mumashandisirwo anosvika akati wandei GHz, ichiita kuti ive yakakodzera yepakati-kumhanya dhijitari, mota radar inotsigira wedunhu, uye general-chinangwa chakakwira-kumhanya kubatanidza.
Kuburikidza neHole uye Via Kutendeseka
Kuwedzerwa kweZ-axis kunoderedza kutsemuka kwedhiramu uye kusimudza mapedhi mumaburi. Kuramba kweCAF kunodzivirira kusimuka kweelectrochemical kutama-density kuburikidza neminda, kuwedzera hupenyu hwesevhisi munzvimbo dzine hunyoro kana dzinopisa.

Dhizaini Mafungiro eITEQ IT-180A
Lamination uye Pre-Bake
Mushure mekurapa oxide (yakasviba kana yebrown), bika mukati memukati pa120 ° C kwemaminetsi mashoma makumi mana kuti udzinge unyoro hwakanyura. Mvura yakasara inokonzeresa delamination inopfungaira panguva yekudzvanya. Chengetedza prepregs munzvimbo inodzorwa (<20 ° C, <50% RH) uye bvumira 12 maawa acclimation isati yarongeka.
Drilling uye Desmear
IT-180A inodhirowa zvakachena neyakajairwa carbide bits. Kune yakakwirira-layer uye inorema-mhangura stacks, deredza kureba kwestack (1 pani ye ≥8 layer) uye bvunza wako mutengesi wechibhorani pakudya/kumhanyisa optimization. Desmear paramita inosiyana kubva kune yakajairwa FR-4-yakajairika marongero anogona undercut resin. Rongedza nemutengesi wako wemakemikari kuti ugadzirise kutenderera kwepermanganate kana kufunga kaviri desmear kupfuura.
Kutungamira-Mahara Reflow Kuenderana
Izvo zvinhu zvinopfuura 260 ° C inotungamira-isina kuyerera pane IPC J-STD-020 zvinodiwa. T260> 60 min uye T288> 20 min inosimbisa kusimba pakurwisana nehukasha hwekupisa profiles. Gwaro repamusoro tembiricha, nguva-pamusoro-liquidus, uye mareti erempu yemarekodhi ekukodzera marekodhi.
High-Frequency Signal Routing
IT-180A's Drk/Df values inotsigira mid-range high-speed digital and automotive radar baseband routing. Kune RF/microwave front-ends dzakasimba (dzinopfuura 10GHz dzine tight insertion loss budgets), tarisa ma laminates akasarudzika ane low-loss akadai se specialty low-loss laminate kana Isola Astra series. Ma hybrid stackups—IT-180A e power/ground layers uye low-loss material equipment ye signal layers—anogona kuenzana mutengo nekushanda.
Manufacturing and Process Guidelines
Stackup Recommendations
Kune 6- kusvika 8-layer madhizaini, shandisa 0.1-0.2mm cores ane 106/1080/2116 prepreg masitayipi zvichienderana nekunangwa impedance uye ukobvu hwekupedzisira. Chengetedza symmetrical kuvaka kudzivirira uta uye kumonyoroka. ITEQ inopa prepreg kuyerera uye gel-nguva data; bvunza izvi kuitira press cycle optimization.
Vacuum Lamination
Vacuum degas stacks kwemaminetsi makumi matatu isati yapisa kubvisa mweya wakavharirwa. Inokurudzirwa kudzvanywa kwedhinda: 350-400 psi (hydraulic) kana 300-400 psi (vacuum-hydraulic). Kupisa kwehuwandu kubva ku80 ° C kusvika ku140 ° C: 1.3-30 ° C / min. Bata pa 180 ° C kweinenge 60 maminetsi kuti uve nechokwadi chekurapa kuzere. Kutonhodza pa ≤3°C/min kuderedza kushushikana kwasara.
Surface Pedzisa Kuenderana
IT-180A inoenderana neENIG, HASL (isina-lead), OSP, uye kunyudza tin/silver kupera. Kune ENIG, simbisa phosphorus yemukati uye plating ukobvu kudzivirira nickel corrosion nyaya. Lead-isina HASL cycles (265°C solder poto) ari mukati mezvinhu zvekupisa kwekugona.
Kuvimbika Testing Cheki
Kumbira zvinotevera kubva kune wako laminate supplier kana kumhanya-mumba: TMA for Tg simbiso, thermal bhasikoro (-40 kusvika +125°C, 500+ cycles), thermal shock (mvura-ku-mvura), munyu pfapfaidzo (pa IPC-TM-650 2.6.14 yemotokari), uye CAF pasi pe5858% yekuongorora CAF/H Document results for customer qualification packages.
ITEQ IT-180A vs. Kukwikwidza High-Tg Zvishandiso
Tafura iri pazasi inoenzanisa IT-180A neIsola 370HR — imwe nzira yakatsanangurwa zvakanyanya muchikamu che high-Tg FR-4.
