The wololera masanjidwe zipangizo zamagetsi pa PCB bolodi ndi yofunika kwambiri ulalo kuchepetsa kuwotcherera zilema! Zigawo ziyenera kupewa madera omwe ali ndi mayendedwe opotoka kwambiri komanso malo opanikizika kwambiri mkati momwe angathere, ndipo masanjidwe ake akhale ofananira momwe angathere.
Pofuna kuti azidzagwiritsa ntchito dera bolodi danga, ine ndikukhulupirira kuti ambiri mapangidwe zibwenzi adzayesa kuika zigawo zikuluzikulu motsutsa m'mphepete mwa bolodi, koma kwenikweni, mchitidwe umenewu adzabweretsa vuto lalikulu kwa kupanga ndi PCBA msonkhano, ndipo ngakhale kutsogolera kulephera kuwotcherera msonkhano o!
Lero, tiyeni tikambirane za masanjidwe a m'mphepete chipangizo mwatsatanetsatane
Chiwopsezo cha masanjidwe a chipangizo cha gulu
01. Kuumba bolodi m'mphepete mphero bolodi
Pamene zigawozo zimayikidwa pafupi kwambiri ndi m'mphepete mwa mbale, chowotcherera chopangira zigawozo chidzaphwanyidwa pamene mbale ya mphero ipangidwa. Nthawi zambiri, mtunda pakati pa chowotcherera chowotcherera ndi m'mphepete uyenera kukhala wamkulu kuposa 0.2mm, apo ayi chowotcherera cha chipangizo cha m'mphepete chidzatulutsidwa ndipo msonkhano wam'mbuyo sungathe kuwotcherera zigawozo.
02. Kupanga mbale m'mphepete V-CUT
Ngati m'mphepete mwa mbale ndi Mose V-CUT, zigawozo ziyenera kukhala kutali ndi m'mphepete mwa mbale, chifukwa mpeni wa V-CUT wochokera pakati pa mbale nthawi zambiri umakhala woposa 0.4mm kuchokera pamphepete mwa V-CUT, mwinamwake mpeni wa V-CUT udzapweteka mbale yowotcherera, zomwe zimapangitsa kuti zigawozo zisamawotchedwe.
03. Zida zosokoneza chigawo
Mapangidwe a zigawo zomwe zimakhala pafupi kwambiri ndi m'mphepete mwa mbale panthawi ya mapangidwe zimatha kusokoneza ntchito ya zida zopangira msonkhano, monga makina opangira mafunde kapena makina otsekemera, posonkhanitsa zigawo.
04. Chipangizocho chimaphwanya zigawo
Kuyandikira chigawocho ndi m'mphepete mwa bolodi, mphamvu yake yaikulu yosokoneza chipangizo chosonkhanitsidwa. Mwachitsanzo, zigawo monga electrolytic capacitors zazikulu, zomwe ndi zazitali, ziyenera kuyikidwa patali ndi m'mphepete mwa bolodi kusiyana ndi zigawo zina.
05. Zigawo za bolodi yaying'ono zawonongeka
Pambuyo pomaliza kusonkhanitsa mankhwala, chodulidwacho chiyenera kupatulidwa ndi mbale. Panthawi yopatukana, zigawo zomwe zili pafupi kwambiri ndi m'mphepete zimatha kuwonongeka, zomwe zingakhale zapakatikati komanso zovuta kuzizindikira ndikuzichotsa.
Zotsatirazi ndikugawana nkhani yopanga za mtunda wa chipangizo cha m'mphepete sikokwanira, zomwe zimabweretsa kuwonongeka kwa inu ~
Kufotokozera zavuto
Zimapezeka kuti nyali ya LED ya chinthu ili pafupi ndi m'mphepete mwa bolodi pamene SMT imayikidwa, yomwe imakhala yosavuta kugwedezeka popanga.
Zotsatira zavuto
Kupanga ndi zoyendetsa, komanso nyali ya LED idzasweka pamene njira ya DIP ikudutsa njira, zomwe zidzakhudza ntchito ya mankhwala.
Kukulitsa vuto
Ndikofunikira kusintha bolodi ndikusuntha LED mkati mwa bolodi. Panthawi imodzimodziyo, idzaphatikizanso kusintha kwa ndondomeko yowunikira kuwala, zomwe zimayambitsa kuchedwa kwakukulu kwa kayendetsedwe ka polojekiti.
Kuzindikira zoopsa za zida zam'mphepete
Kufunika kwa chigawo kamangidwe kamangidwe ndi zoonekeratu, kuwala zingakhudze kuwotcherera, zolemetsa mwachindunji kutsogolera chipangizo kuwonongeka, kotero kuonetsetsa 0 mavuto kapangidwe, ndiyeno bwinobwino kupanga?
Ndi ntchito yosonkhanitsa ndi kusanthula, BEST ikhoza kufotokozera malamulo oyendera malinga ndi magawo a mtunda kuchokera pamphepete mwa mtundu wa chigawocho. Ilinso ndi zinthu zowunikira mwapadera pamapangidwe a zigawo za m'mphepete mwa mbale, kuphatikiza zinthu zingapo zowunikira mwatsatanetsatane monga chipangizo chapamwamba mpaka m'mphepete mwa mbale, chipangizo chotsika mpaka m'mphepete mwa mbale, ndi chipangizo chopita m'mphepete mwa njanji yamakina, yomwe imatha kukwaniritsa zofunikira pakuwunika kwakutali kwa chipangizocho kuchokera m'mphepete mwa mbale.
