Automotive Semiconductor PCB: Dhizaini uye Kugadzira Kwemagetsi Emagetsi

ziviso

Semiconductor tekinoroji inoshanda semusana wemazuva ano emagetsi emagetsi emagetsi, achigonesa masisitimu akakosha akadai seEV inverters, onboard charger, DC-DC converters, uye ADAS magetsi module. Aya maapplication anoda edunhu mabhodhi anokwanisa kubata yakakwira density iripo, yakakwira tembiricha yekushanda, uye kuenderera mberi kwemechani vibration uchichengetedza kuita kwemagetsi chaiko.

Dambudziko rinowedzera kupfuura basa rekutanga kusanganisa kutonga kwemafuta, kuparadzaniswa kwemagetsi, uye kuvimbika kwenguva refu pasi pemamiriro ekushushikana kwemotokari. Specialised mota semiconductor PCBs vanoita basa rakakosha mukuona kuita kwakavimbika kweakakwira-simba mota masisitimu.

Zvemotokari Semiconductor PCB mune Simba Electronics Zvishandiso

Kugovera Simba uye Chiratidzo Kutendeseka

Automotive semiconductor PCBs mumamodules emagetsi anoshanda matatu ekutanga mabasa: kugovera mafungu akakwira pakati pemidziyo yemagetsi, kuchengetedza chiratidzo chekuzviparadzanisa pakati pekutonga uye masimba emasimba, uye kupa nzira dzinopisa dzekubvisa kupisa. MuSiC-based inverter dhizaini, iyo PCB inoita seyakavakirwa nheyo yekubatanidza switching zvishandiso kumabhangi ecapacitor uku uchifambisa masaini egedhi dhiraivha ane kushoma inductance.

Design Zvinodiwa Kuenzanisa

MaPCB emagetsi emagetsi anoda ukobvu hwemhangura hunobva pamaounces maviri kusvika matanhatu zvichienzaniswa ne1-ounce standard mumabhodhi ekudzora. Tembiricha dzekushanda dzinogara dzichipfuura 125°C pedyo nemasemiconductor emagetsi, zvichida zvinhu zvine tembiricha yekuchinja kwegirazi iri pamusoro pe170°C. EV inverter PCB traces dzinofanira kubata current densities kusvika ku30A pa millimeter trace width, zvichida ongororo yekunyatsoongorora kupisa.

Base Material Selection

Maseketi ekutonga anowanzo shandisa ma FR-4 laminates kuti ashandise mari yakawanda, nepo ma power stages achida ma metal-core substrates kana insulated metal substrates (IMS) kuti awedzere kupisa. Magadzirirwo ePCB ane thermal conductivity yakakwira anosanganisira hybrid constructions apo ma power layers anoshandisa simbi cores nepo ma signal layers achishandisa zvinhu zve dielectric zvemazuva ano.

Hunhu hwakakosha hunosanganisira:

• Aluminium IMS substrates -Thermal conductivity ye1-2 W/mK ine dielectric isolation layer.
• Copper-base zvinhu - Thermal conductivity inodarika 180 W/mK yezvinodiwa zvekupisa zvakanyanya.
• Standard FR-4 laminates - Thermal conductivity ye 0.3 W / mK, inokodzera zviratidzo zvekugadzirisa zvikamu.

Yakakora Copper uye Thermal Management

Yakakora yemhangura yePCB mashandisirwo anoshandisa 3 kusvika 6-ounce huremu hwemhangura kune makuru emagetsi ekutsvaga, neplating ichiwedzera ukobvu munzvimbo dzakakosha. Thermal vias akaiswa pasi pemagetsi zvishandiso zvinogadzira nzira dzekupisa dzakamira kune simbi cores kana ekunze heatsinks. Mari yemhangura-yakasimba mhangura inoisa yakaiswa muPCB-isa pfungwa pakubvisa kupisa zvakananga pasi pesimba-simba semiconductors.

Dielectric Zvivakwa

Yakakwira-frequency gedhi dhiraivha masaini anoda dielectric zvinhu zvine yakaderera dissipation chinhu uye yakagadzikana dielectric inogara pane tembiricha. Polyimide uye ceramic-yakazadzwa zvinhu zvinochengetedza magetsi zvivakwa patembiricha yakakwira apo ichipa kugadzikana kwemakanika kunodiwa kune nharaunda dzemotokari. Signal layer impedance control inova yakakosha muSiC neGaN maapplication uko kumhanyisa kumhanya kunoburitsa mareti emupendero anopfuura 50V pananosecond.

Automotive Semiconductor PCB Dhizaini yeSiC uye GaN Modules

High-Frequency Switching Zvinodiwa

SiC simba module PCB magadzirirwo anofanirwa kudzikisa parasitic inductance mu commutation loop kudzvanya voltage overshoot panguva yekuchinja shanduko. Gedhi drive trace impedance inoda kuenderana ne50 ohms nekushivirira kwakasimba, nepo loop nzvimbo pakati pemidziyo yemagetsi uye decoupling capacitors dzinofanira kuramba dziri pazasi 5 mativi masendimita.
