Kubara imikorere yubushyuhe bwibishushanyo mbonera bya PCB

Muri iyi blog, tuzasesengura uburyo nibiharuro bisabwa kugirango tumenye imikorere yubushyuhe bwibishushanyo mbonera bya PCB.

Mugushushanya icyapa cyumuzingo cyacapwe (PCB), kimwe mubintu byingenzi injeniyeri bakeneye gusuzuma ni imikorere yubushyuhe.Hamwe niterambere ryihuse ryikoranabuhanga hamwe no gukomeza gukenera ibikoresho byinshi bya elegitoroniki kandi byoroshye, gukwirakwiza ubushyuhe muri PCB byabaye ikibazo gikomeye. Ibi ni ukuri cyane cyane kubishushanyo mbonera bya PCB bihuza ibyiza byimbaho ​​zumuzingi zikomeye.

Imikorere yubushyuhe igira uruhare runini mukwemeza kwizerwa no kuramba kwibikoresho bya elegitoroniki.Kwiyongera k'ubushyuhe bukabije birashobora gukurura ibibazo bitandukanye, nko kunanirwa kw'ibigize, kwangirika kw'imikorere, ndetse no guhungabanya umutekano. Kubwibyo, ni ngombwa gusuzuma no kunoza imikorere yubushyuhe bwa PCBs mugice cyo gushushanya.

Hano hari intambwe zingenzi zo kubara imikorere yubushyuhe bwibishushanyo mbonera bya PCB:

1. Menya imiterere yubushyuhe: Icya mbere, ni ngombwa gukusanya amakuru akenewe kubyerekeranye nubushyuhe bwumuriro nubushobozi bwihariye bwubushyuhe bwibikoresho bikoreshwa mubishushanyo mbonera bya PCB.Ibi birimo ibice byayobora, ibyumba byiziritse, nibindi byongeweho ubushyuhe cyangwa vias. Ibiranga bigena ubushobozi bwa PCB bwo gukwirakwiza ubushyuhe.

2. Kubara Ubushyuhe bwa Thermal: Intambwe ikurikira ikubiyemo kubara ubushyuhe bwumuriro bwibice bitandukanye hamwe nintera muburyo bukomeye bwa PCB.Kurwanya ubushuhe ni igipimo cyukuntu ibintu cyangwa interineti ikora neza. Bigaragarira mubice bya ºC / W (selisiyusi kuri Watt). Hasi yubushyuhe bwumuriro, nibyiza kohereza ubushyuhe.

3. Menya inzira yubushyuhe: Menya inzira zikomeye zumuriro mubishushanyo mbonera bya PCB.Izi ninzira inzira ubushyuhe butanga ingendo. Ni ngombwa gusuzuma ibice byose bitanga ubushyuhe nka IC, ibikoresho byamashanyarazi, nibindi bikoresho byose bitanga ubushyuhe. Gisesengura inzira yubushyuhe buva mubushyuhe bugana ibidukikije bikikije kandi urebe ingaruka zibikoresho bitandukanye hamwe niyi nzira.

4. Kwigana no gusesengura ubushuhe: Koresha porogaramu yo gusesengura ubushyuhe kugirango wigane ikwirakwizwa ryubushyuhe muburyo bukomeye bwa flex.Ibikoresho byinshi bya software, nka ANSYS Icepak, SOLIDWORKS Flow Simulation cyangwa Mentor Graphics FloTHERM, itanga ubushobozi buhanitse bwo kwerekana neza no guhanura imyitwarire yubushyuhe. Ibigereranirizo birashobora gufasha kumenya ahantu hashyushye, gusuzuma uburyo butandukanye bwo gushushanya no guhindura imikorere yubushyuhe.

5. Gushyushya ubushyuhe bwa sink: Niba bikenewe, icyuma gishyushya kirashobora gushyirwamo imbaraga kugirango ubushyuhe bwumuriro bwibishushanyo mbonera bya PCB.Ibyuma bishyushya byongera ubuso buboneka kugirango ubushyuhe bugabanuke kandi bitezimbere ihererekanyabubasha muri rusange. Ukurikije ibisubizo byigero, hitamo igishushanyo mbonera gikwiye, hitabwa kubintu nkubunini, ibikoresho, n'imiterere.

6. Suzuma ubundi buryo: Suzuma ingaruka zo guhitamo ibintu bitandukanye kumikorere yubushyuhe bwibishushanyo mbonera bya PCB.Ibikoresho bimwe bitwara ubushyuhe neza kurenza ibindi kandi birashobora kuzamura cyane ubushobozi bwo gukwirakwiza ubushyuhe. Reba amahitamo nka ceramic substrates cyangwa ibikoresho bya PCB bitwara ubushyuhe, bishobora gutanga imikorere myiza yubushyuhe.

7. Gupima ubushyuhe no kugenzura: Nyuma yo gushushanya no kwigana birangiye, ni ngombwa kugerageza no kugenzura imikorere yumuriro nyirizinaIkomeye-flex PCB prototype.Koresha kamera yumuriro cyangwa thermocouples kugirango ufate ibipimo byubushyuhe kumwanya wingenzi. Gereranya ibipimo no kwigana no gusubiramo igishushanyo nibiba ngombwa.

Muncamake, kubara imikorere yubushyuhe bwibishushanyo mbonera bya PCB ni umurimo utoroshye usaba gutekereza neza kubintu bifatika, kurwanya ubushyuhe, n'inzira zumuriro.Mugukurikiza intambwe yavuzwe haruguru no gukoresha porogaramu igezweho yo kwigana, injeniyeri zirashobora guhindura ibishushanyo mbonera kugirango bigabanuke neza kandi bitezimbere muri rusange kwizerwa no gukora ibikoresho bya elegitoroniki.

Wibuke, gucunga ubushyuhe nibintu byingenzi byubushakashatsi bwa PCB, kandi kubyirengagiza bishobora kugira ingaruka zikomeye.Mugushira imbere kubara imikorere yubushyuhe no gukoresha tekinike ikwiye, injeniyeri arashobora kwemeza kuramba no gukora ibikoresho bya elegitoroniki, ndetse no mubisabwa.
