Momwe mungasankhire zolumikizira zoyenera pa board-to-board

Ndiye posankha cholumikizira, ndi malingaliro ati omwe tiyenera kuwona cholumikizira choyenera kugwiritsa ntchito hardware?

1. Zikhomo, Pitch

Nambala ya pini ndi malo a pini ndiye maziko oyambira kusankha cholumikizira. Ndi manambala angati a pini a zolumikizira zomwe mumasankha zimatengera kuchuluka kwa ma sign omwe akuyenera kulumikizidwa. Kwa zolumikizira zigamba zina, pini ya mizere yachigamba yomwe ikuwonetsedwa pachithunzi chotsatira sichiyenera kukhala mapini ambiri. Chifukwa pakuwotcherera kwa makina a SMT, chifukwa cha kutentha kwambiri, pulasitiki yolumikizira imatenthedwa ndikupunduka, ndipo kuphulika kwapakati kumayambitsa kuwotcherera kwa pini. Kumayambiriro kwa chitukuko cha pulogalamu yathu ya P800Flash, tidagwiritsa ntchito pini ndi bar kuti tilumikizane ndi bolodi, ndipo zotsatira zake zinali kuti pini ya pini yachiwonetsero idawokeredwa pamalo akulu. Pambuyo pochotsa zikhomo ziwirizo ndi theka la chiwerengero cha zikhomo, panalibe kuwotcherera kwabodza.

Masiku ano, zida zamagetsi zikukula molunjika ku miniaturization ndi kulondola, ndipo masitayilo a pini a zolumikizira amachokera ku 2.54mm mpaka 1.27mm mpaka 0.5mm. Kuchepa kwa mipata ya pini, m'pamenenso ntchito yopangira imakwera. Kutalikirana kwa mapini kuyenera kutsimikiziridwa ndi momwe kampani ikupangira, komanso kufunafuna kwapang'onopang'ono

2. Kuchita kwamagetsi

Kuchita kwamagetsi kwa cholumikizira makamaka kumaphatikizapo: malire apano, kukana kukhudzana, kukana kutsekereza ndi mphamvu zamagetsi. Mukagwirizanitsa magetsi apamwamba, tcherani khutu ku malire amakono a cholumikizira; Mukatumiza ma siginecha apamwamba kwambiri monga ma LVDS ndi ma PCIe, tcherani khutu kukana kulumikizana. Cholumikizira chikuyenera kukhala chocheperako komanso chosasunthika, nthawi zambiri makumi a mΩ mpaka mazana a mΩ.

3. Kuchita kwa chilengedwe

Ntchito zachilengedwe za cholumikizira makamaka zikuphatikizapo: kukana kutentha, kukana chinyezi, kukana kutsitsi mchere, kugwedezeka, kukhudzidwa ndi zina zotero. Sankhani molingana ndi malo ogwiritsira ntchito. Ngati malo ogwiritsira ntchito ndi onyowa, kukana chinyezi cha cholumikizira ndi kukana kutsitsi kwa mchere kumafunika kuti tipewe dzimbiri zazitsulo zolumikizira cholumikizira. M'munda wowongolera mafakitale, kukana kwamphamvu kwa cholumikizira kumafunika kukhala kokwezeka, kuti cholumikizira chisagwe pakugwedezeka.

4. Makina katundu

Zomwe zimapangidwira za cholumikizira zimaphatikizapo plugging mphamvu, anti-stay mechanical, etc. Mawotchi otsutsa-kukhala ofunikira kwambiri kwa cholumikizira, kamodzi atayikidwa, ndiye kuti angayambitse kuwonongeka kosasinthika kwa dera!

Mphamvu yolowetsa imagawidwa mu mphamvu yolowetsa ndi mphamvu yolekanitsa. Pali zoperekedwa m'miyezo yoyenerera ya mphamvu yowonjezera yowonjezera ndi mphamvu yochepa yolekanitsa, kuchokera kumalo ogwiritsira ntchito, mphamvu yoyikapo iyenera kukhala yaying'ono, mphamvu yolekanitsa iyenera kukhala yaikulu. Mphamvu yolekanitsa yaying'ono idzachepetsa kudalirika kwa kukhudzana, koma kwa zolumikizira zomwe nthawi zambiri zimafunikira kulumikizidwa ndi kutulutsidwa, mphamvu yolekanitsa yochulukirapo idzawonjezera zovuta zotulutsa ndikuchepetsa moyo wamakina.
