Rimwe na rimwe, byose bisaba kubaka ikintu gishimishije ni ugushyira hamwe ibice bishaje hamwe muburyo butandukanye.
Icyamamare WS2812B gifite uburebure bwa mm 1,6, bibaho kuba ubunini bwa PCB bukoreshwa cyane. Ukoresheje EasyEDA, [Sayantan] wateguye matrike 8 × 8 hamwe na WS2812B yahinduwe. Hongeweho agace gato gato kugirango habeho guterana neza kuri LED, hamwe nudupapuro twimuriwe inyuma yikibaho hanze yikibanza hanyuma inshingano zabo zirahindurwa. PCB yateranijwe hasi hasi, kandi amakariso yose agurishwa nintoki. Kubwamahirwe, ibi birema ikiraro kinini cyane cyagurishijwe, aricyo byongera gato ubunini rusange bwikibaho, kandi ntibishobora kuba bibyara umusaruro ukoresheje gutoranya gakondo no guteranya.
Tumaze kubona uburyo bumwe busa kubice bya PCB ukoresheje PCB zingana. Ababikora batangiye no gushira ibice muri PCB nyinshi.
Ibi bigomba kuba ibipimo bishya byo gupakira ibintu! Ukoresheje ikibaho gihenze cya etaje enye, ntidukeneye ahantu hanini cyane, kandi birashobora guhita byinjizwa cyangwa kugurishwa nintoki kugirango dusimbuze DIP.Ushobora gushiraho hejuru ya inductor hejuru hejuru ya chip muri PCB yibigize byose bya pasiporo. Ubuvanganzo bushobora gutanga ubufasha bwubukanishi.
Gukata birashobora guhindagurika gato cyangwa kumera nka feri kandi bigakorwa na lazeri, bityo rero guhuza igice ntibisaba neza cyane kandi birashobora gukorwa nubushyuhe no gusunika hanze kurundi ruhande.
Ku kibaho kimeze nk'ifoto iri mu ngingo, sinkeka ko gikeneye kurenga 2L.Niba ushobora kubona LED muri pake ya "gull-wing", urashobora kubona byoroshye ikintu cyoroshye kandi cyoroshye.
Ndabaza niba bishoboka gukoresha urwego rwimbere kugirango wirinde kugurisha kumurongo winyuma (mugukora agace gato kugirango ugere kuriyi nzego, bityo uwagurishije azaba menshi.
Cyangwa ukoreshe paste yo kugurisha hamwe nitanura. Koresha mm 2 FR4, kora umufuka wa mm 1,6 zubujyakuzimu, shyira padi hepfo yimbere, ushyireho paste yo kugurisha hanyuma uyishyire mu ziko.Bob ni murumuna wa so, kandi LED zirahinduka.
Mbere yo gusoma ingingo yose, ndatekereza ko ihererekanyabubasha ryiza rizibandwaho niyi hackers. Shyira umuringa wibibaho bya n-layer, shyira gusa ubwoko ubwo aribwo bwose bwubushyuhe inyuma, hamwe na padi yumuriro (utazi the ijambo rikwiye).
Urashobora guhinduranya LED kumurongo wa firime ya polyimide (Kapton) aho gucuruza intoki ayo masano yose kuruhande rwinyuma: ibirometero 10 gusa, bishobora kuba byoroshye kuruta kugurisha amaboko.
Ntabwo imiterere rusange yiyi paneli idakoresha insimburangingo zoroshye? Ibyanjye ni nkibi.Ibice bibiri, nuko rero hari ubushyuhe bwo gukwirakwiza-bukenewe cyane kuriyi ntera nini. Mfite 16 × 16, irashobora gukuramo byinshi Bya i.
Nahitamo kubona umuntu ashushanya aluminiyumu ya PCB-amide ikibaho cyometse ku gipande cya aluminium.
Imirongo yumurongo (1-D) ikunze kuboneka kuri substrate yoroheje.Ntabwo nabonye ikibaho cyibice bibiri hamwe niyi miterere.Haba hari aho uhurira nuwo wavuze?
PC ya aluminiyumu yoroheje PCB ifite akamaro nkicyuma gishyuha, ariko iracyashyuha: uracyakeneye gukwirakwiza ubushyuhe ahantu runaka amaherezo.Kubera imbaraga zanjye zo hejuru, nashizemo polyimide yoroheje (ntabwo ari amide!) Substrate kuri a binini binini byashushe hamwe na epoxy yumuriro.Ntabwo nkoresha ubwoko bwumuti wunvikana.Nubwo hariho convection gusa, biroroshye kujugunya> 1W / cm ^ 2.Nziruka kuri 4W / cm ^ 2 muminota mike kuri gihe, ariko niyo ifite cm 3 zimbitse, bizaba biryoshye cyane.
Muri iki gihe, PCBs zometse ku mbaho ​​z'umuringa cyangwa aluminiyumu ziramenyerewe cyane.Ku bintu nkoresha ubwanjye, nasaba inama y'umuringa byoroshye guhuza kuruta aluminium.
Keretse niba wagurishije igikoresho kumuringa (nukuvuga, niba bibaye ngombwa), nsanga epoxy ishyushye ihuza aluminium ari nziza cyane kuruta umuringa. Nabanje gushiramo aluminiyumu hamwe na 1N NaOH igisubizo cyamasegonda 30, hanyuma kwoza amazi ya deionion hanyuma yumisha neza. Mbere yuko okiside yongera gukura, irahuzwa muminota mike.Damn hafi yumubano utavogerwa.
Ukoresheje urubuga na serivisi zacu, wemera byimazeyo gushyira ibikorwa byacu, imikorere hamwe na kuki yamamaza. Wige byinshi
