Mastering Rapid PCB Prototyping yokhala ndi Fine Pitch Components

Tsegulani:

Rapid PCB prototyping, makamaka kuphatikiza kwa zigawo zomveka bwino, zimafunikira ukatswiri komanso kulondola. Pamene teknoloji ikupitirirabe patsogolo, kupanga ma boardboard kumakhala kovuta komanso kovuta. Ali ndi zaka zopitilira 15 pantchitoyi, Capel ndi kampani yotsogola yomwe imaphatikiza ukadaulo waukadaulo komanso luso lokhazikika kuti lipereke mayankho osayerekezeka.Mu positi iyi yabulogu, tilowa munjira, zovuta, ndi njira zabwino zowonera mwachangu PCB yokhala ndi zida zomveka bwino, ndikuwunika luso lopanga la Capel.

Phunzirani za zigawo zomveka bwino:

Zigawo zomveka bwino zimagwira ntchito yofunika kwambiri pazida zamakono zamakono chifukwa zimathandizira kutumizirana mwachangu, kuyendetsa pang'ono, komanso kugwira ntchito bwino. Kutalikirana kwa pini kwa zigawozi ndi zosakwana 0.8 mm, zomwe zimapangitsa kuyika kwawo pa PCB kukhala kovuta kwambiri. Chifukwa chake, ndikofunikira kutengera njira ndi njira zina zowonetsetsa kuti ma prototyping apambana.

Zida zamakono za PCB zopangira ma prototyping mwachangu:

Kuti mugwiritse ntchito bwino zigawo zomveka bwino pakujambula mwachangu kwa PCB, zida zapamwamba za PCB ziyenera kugwiritsidwa ntchito. Mapulogalamu monga Altium Designer, Eagle kapena KiCad amapereka zinthu monga kuyika kwachindunji, kusanthula kukhulupirika kwa chizindikiro ndi ntchito zodzipangira okha, zomwe zimathandiza kwambiri kukhathamiritsa kwa masanjidwe. Gulu la akatswiri a Capel ali ndi luso logwiritsa ntchito zida izi kuti zitsimikizire kuti zili zolondola kwambiri panthawi ya prototyping.

Zinthu zofunika kuziganizira popanga zigawo zomveka bwino:

Mukamapanga masanjidwe a PCB okhala ndi zigawo zomveka bwino, ndikofunikira kuganizira zinthu zina kuti muwonetsetse kuti magwiridwe antchito ndi opangidwa bwino. Nazi zina zofunika kuziganizira:

1. Mapangidwe a Pad: Kukula kwa pedi ndi mawonekedwe ndizofunika kwambiri pazitsulo zoyenera komanso kukhudzana kwamagetsi ndi chigawocho.Akatswiri odziwa bwino ntchito a Capel amapanga mapepala mosamala potengera zofunikira zenizeni za zigawo zomveka bwino, zomwe zimapereka kugulitsa bwino komanso kudalirika.

2. Ma trace ndi ma vias: Zizindikiro zothamanga kwambiri zomwe zimadutsa m'zigawo zomveka bwino zimafuna njira yosamala kuti muchepetse phokoso, kuchepetsa ma siginecha, ndi kusagwirizana kwamphamvu.Njira zoyenerera poyika ndi kufufuza njira monga kufananitsa utali ndi njira zosiyanitsira zimathandizira kusunga chizindikiro.

3. Kasamalidwe ka kutentha: Zigawo zomveka bwino zimapanga kutentha kwakukulu panthawi yogwira ntchito.Kuwongolera kokwanira kwa kutentha pogwiritsa ntchito zipinda zotentha, mpweya wotentha, kapena kuika mapepala otentha pansi pa zigawo zikuluzikulu ndizofunikira kwambiri kuti tipewe kutenthedwa ndi kuonetsetsa kudalirika kwa nthawi yaitali.

4. Design for Manufacturing (DFM): Gwirani ntchito ndi gulu la Capel lodziwa zambiri panthawi ya mapangidwe a PCB kuti muwonetsetse kuti zosankha zapangidwe zikugwirizana ndi zomwe amapanga.Kuwongolera mapangidwe apangidwe kumathandizira kuchepetsa zolakwika za prototyping ndikuwongolera magwiridwe antchito onse.

Prototyping zovuta ndi mayankho:

Kujambula mwachangu kwa PCB yokhala ndi zigawo zomveka bwino kumabweretsa zovuta zapadera. Komabe, ndi chidziwitso chochuluka cha Capel komanso ukadaulo wothandiza, zovutazi zitha kuchepetsedwa mosavuta.

1. Kupeza zinthu: Zida zomveka bwino nthawi zambiri zimakhala ndi nthawi yayitali yotsogolera kapena kupezeka pang'ono, zomwe zimapangitsa kufufuza kwawo kukhala kovuta kwambiri.Maubwenzi ambiri a Capel ogulitsa katundu ndi maubwenzi olimba amatsimikizira kuti nthawi yake ifika pazigawo zapamwamba, kuonetsetsa kuti palibe zosokoneza.

2. kuwotcherera: kuwotcherera zigawo zabwino phula kumafuna mwatsatanetsatane mkulu.Capel imagwiritsa ntchito matekinoloje apamwamba a msonkhano monga ma ovuni obweranso omwe ali ndi mbiri ya kutentha, makina oyika okha ndi kuyang'anira phala la solder kuti atsimikizire zolumikizana bwino.

3. Kuyesa ndi Kuyang'anira: Pa gawo la prototyping, kuyezetsa mozama ndikuwunika ndikofunikira kuti muwone zolakwika zomwe zingakhalepo monga milatho ya solder, kutsegulira, kapena miyala yamanda.Capel amafufuza mosamalitsa pogwiritsa ntchito makina opangira kuwala (AOI), kuyendera ma X-ray ndi kuyesa malire kuti atsimikizire kuti ma prototypes ndi opanda cholakwika.

Kuthekera kosayerekezeka kwa Capel:

Kudzipereka kwa Capel pakuchita bwino kwambiri komanso kupita patsogolo kwaukadaulo kwapangitsa kuti akhale mnzake wodalirika pamakampani opanga PCB.Ukatswiri waukulu wa kampaniyo, wothandizidwa ndi zida zamakono zopangira zinthu komanso kutsatira miyezo yapadziko lonse lapansi, umathandizira kuti ipereke luso lopanga zinthu zosayerekezeka.

Pomaliza:

Kujambula mwachangu kwa ma PCB pogwiritsa ntchito zigawo zomveka bwino kumafuna chidziwitso chapadera ndi luso. Pokhala ndi zaka 15 zakubadwa, ukatswiri komanso kudzipereka pakupanga zatsopano, Capel ali ndi mwayi wapadera wothana ndi zovuta izi ndikupitilira zomwe amayembekeza.Kugwira ntchito ndi Capel kumatsimikizira ma prototypes opanda cholakwa, njira zopangira zogwirira ntchito komanso chithandizo chosayerekezeka pagawo lililonse la polojekiti. Khulupirirani akatswiri a Capel kuti apangitse chithunzi chanu cha PCB kukhala chamoyo ndikukwaniritsa zofunika kwambiri pamakampani amakono amagetsi.
