PCB yemhangura inorema yekupa magetsi ikozvino uye kupisa

ziviso

Tekinoroji yePCB yemhangura ine mhangura , inotsanangurwa neukobvu hwemhangura hwe3 oz (105 μm) kana kupfuura, yave yakakosha kune zvigadzirwa zvemagetsi zvemaindasitiri zvemazuva ano. Mabhodhi aya edunhu ane hunyanzvi anotarisana nematambudziko makuru ekushandiswa kwemagetsi emagetsi akakwira apo maPCB akajairwa anotadza kuita basa rakakwana.

Mumaindasitiri emagetsi emagetsi uye inverter masisitimu, inorema mhangura PCB yemagetsi ekushandisa inogonesa kushanda kwakavimbika pasi pemagetsi akanyanya uye nekupisa kunetseka uku uchichengetedza kuvimbika kwechimiro. Ichi chinyorwa chinoongorora dzakakosha dhizaini paramita uye kufunga kwekugadzira kune inoda nharaunda maindasitiri.

Izvo Zvinodiwa zveMaindasitiri Simba uye Inverter Systems

High Current uye Power Density Zvinodiwa

Masimba emagetsi emaindasitiri, madhiraivha emota, uye michina yekuwedera zvinoshanda padanho razvino izvo zvinounza kurasikirwa kukuru kweI²R uye huwandu hwekupisa. Magadzirirwo ePCB emagetsi emagetsi anofanirwa kugamuchira huwandu hwemagetsi hunogona kukonzera kuti mabhodhi akajairwa apise zvakanyanya kana kuti aputsike. Dhizaini yePCB yeInverter yemadhiraivha anochinja-chinja anogara achibata mazana emaampere kuburikidza nemagadzirirwo akakomberedzwa, zvichigadzira matambudziko ekutonga kupisa anoda mhinduro dzePCB dzemhangura dzakakora.

Environmental uye Operational Stress

Mamiriro enzvimbo dzeindasitiri ari pasi pemabhodhi edunhu kuti awedzere kupisa bhasikoro, mechanical vibration, uye kuratidzwa kwemakemikari. Power modules munzvimbo dzekugadzira dzinoshanda nguva dzose pakudziya kwakakwirira uku ichichengetedza kuparadzaniswa kwemagetsi pakati pezvikamu zvepamusoro-voltage. Zvivako zvechinyakare zvePCB zvinoshaya kupisa kwekupisa uye kusimba kwemechini inodiwa kuti ivimbike nharaunda yeindasitiri, zvichikonzera kukundikana nguva isati yakwana mumishini-yakakosha magetsi ekupa masisitimu.

Nei Heavy Copper PCB yeMagetsi Ekupa Mashandisirwo

High Current Carrying Capacity

Heavy copper PCB zvivakwa zvinobvumira yakafara conductor nzira pasina kuwedzera bhodhi saizi, yakananga kudzikisa kurasikirwa kwekupokana uye kudonha kwemagetsi. Iyo yakawedzera mhangura yakawanda inogovera ikozvino zvakanyanya zvakaenzana kune yakakwira ikozvino PCB pamusoro, kudzivirira kupisa kwenzvimbo kunoshatisa majoini ekutengesa uye kuvimbika kwechikamu:

Peji rino rakaganhurirwa kumabhodhi emagetsi ane simba remagetsi akawanda anoda mhangura inorema. Kune boka remabhodhi akajairika, tanga nekutarisa bhodhi remagetsi ; pakuisa mapurasitiki, kuchekerera, uye kugona kugadzirwa, shandisa kugadzirwa kwePCB yemhangura inorema.

• Yakaderedzwa I²R kurasikirwa -Yakakora mhangura inodzikisira kudziyisa munzira dzekutanga dzazvino.
• Lower voltage inodonha - Enhanced conductivity inochengetedza yakagadzikana yekushanda voltages pasi pemutoro.
• Kunyangwe kugovera ikozvino -Kuteedzera kwakakura kunodzivirira nzvimbo dzinopisa uye kushushikana kwekushisa.

Superior Thermal Management

Iyo yakakwidziridzwa yekupisa conductivity yemhangura yakakora inogadzira nzira dzinoshanda dzekuparadzira kupisa kubva kune simba semiconductors kuenda kumabhodhi ebhodhi kana nzvimbo dzinokwira. Heavy copper PCB yemamodule emagetsi ekupa magetsi anoita seyakasanganiswa kupisa singi, ichideredza tembiricha yekusangana muIGBTs, MOSFETs, uye diode emagetsi. Uku kuvandudzwa kwekuita kwekupisa kunowedzera hupenyu hwechikamu uye inogonesa yakakwirira simba density dhizaini mune inverter application.

Kuwedzerwa Mechanical Simba

Iyo yakawedzera mhangura yakawanda inosimbisa zvimiro zvebhodhi kurwisa warping panguva yekuyerera uye kupisa bhasikoro. Yakaputirwa-kuburikidza nemakomba ane inorema yemhangura madhiramu anoratidza kupikisa kwepamusoro kune kupisa kwekushushikana kwekutyoka zvichienzaniswa neyakajairwa zvivakwa. Kuvimbika kwePCB mukumisikidzwa kwemaindasitiri kwakakwira-vibration kunoenderana neiyi mechaniki yekusimbisa, kunyanya mumabhodhi makuru akatakura zvinhu zvinorema zvemagetsi.

Dhizaini Mafungiro eHeavy Copper PCB Power Supply

Copper Ukobvu Sarudzo

Kusarudza huremu hwakakodzera hwemhangura kunoda kuongororwa kwemazinga akasimba ezvino uye zvipingamupinyi zvekupisa. PCB dhizaini yemamodule emagetsi anowanzo shandisa 3 oz mhangura yepakati-simba maapplication anosvika 50A, nepo epamusoro-simba inverters anogona kutsanangura 6-10 oz kune ekutanga nzira dzazvino.
