01 Kuki Puzzle
Nyuma yumurongo wumuzunguruko umaze gukorwa, ibice bigomba gushyirwa kumurongo wa SMT chip.Buri ruganda rutunganya SMT ruzerekana ubunini bukwiye bwumuzunguruko ukurikije ibisabwa byo gutunganya umurongo.Kurugero, ingano ni nto cyane cyangwa nini cyane, kandi umurongo wo guterana urakosowe.Ibikoresho byubuyobozi bwumuzunguruko ntibishobora gukosorwa.
Noneho ikibazo kivutse, bigenda bite niba ubunini bwikibaho cyumuzunguruko ubwacyo ari gito ugereranije nubunini bwatanzwe nuruganda?Nukuvuga ko dukeneye gushyira hamwe ikibaho cyumuzunguruko hanyuma tugateranya imbaho nyinshi zumuzingi mubice byose.Kwishyiriraho birashobora kunoza imikorere haba mumashini yihuta yo gushira no kugurisha imiraba.
02 Ibisobanuro
Ibipimo
a.Kugirango byoroherezwe gutunganywa, impande zomwanya cyangwa impande zubukorikori zigomba kuba R-chamfer.Mubisanzwe, impande enye zingana ni Φ5.
b.Iyo ingano yubuyobozi iri munsi ya 100mm × 70mm, PCB igomba guterana (reba Ishusho 3.1).
Ibipimo by'ibipimo bya puzzle:
Uburebure L: 100mm ~ 400mm
Ubugari W: 70mm ~ 400mm
PC PCB idasanzwe
PCBs ifite imiterere idasanzwe kandi nta jigs igomba kugira impande zubukorikori.Niba PCB ifite ibyobo bifite ubunini burenze cyangwa bungana na 5mm × 5mm, ibyobo bigomba kuzuzwa mugihe cyashizweho kugirango birinde kugurisha no guhindura ikibaho mugihe cyo kugurisha.Igice cyuzuzanya nigice cyambere PCB kigomba kuba kuruhande rumwe Guhuza no kugikuraho nyuma yo kugurisha umuraba (reba Ishusho 3.2)
Iyo ihuriro riri hagati yimikorere na PCB ni V-shusho ya V, intera iri hagati yuruhande rwinyuma rwibikoresho na V-shusho ya V ni mm2mm;iyo ihuriro riri hagati yimikorere na PCB ni umwobo wa kashe, ibikoresho numurongo ntibyemewe gutondekwa muri 2mm bikikije umwobo.
Puzzle
Icyerekezo cya jigsaw kigomba kuba gishushanyije nicyerekezo cyuruhande rutanga.Iyo ingano idashobora kuzuza ibisabwa hejuru yubunini bwashyizweho, ibidasanzwe ni.Mubisanzwe bisaba "V-GUCA" cyangwa umubare wumurongo wa kashe ≤ 3 (usibye ibyuma byoroheje), reba Ishusho 3.4
Ku kibaho kidasanzwe, witondere isano ihuza ikibaho cyumukobwa ninama yumukobwa, kandi ugerageze gukora ihuriro kuri buri ntambwe yatandukanijwe kumurongo, nkuko bigaragara ku gishushanyo cya 3.5.
03 pcb puzzle ibintu icumi byambere bikeneye kwitabwaho
Mubihe bisanzwe, umusaruro wa PCB uzitwa icyo bita Panelisation (Panelisation), ikigamijwe nukwongera umusaruro wumurongo wa SMT, hanyuma PCB PCB, ni ubuhe buryo dukwiye kwitondera?Reka turebere hamwe.
1. Ikadiri yo hanze (clamping edge) ya puzzle ya PCB igomba gufata igishushanyo gifunze kugirango irebe ko puzzle ya PCB itazahinduka nyuma yo gukosorwa kuri fixture.
2. Imiterere ya puzzle ya PCB iri hafi ya kare bishoboka.Birasabwa gukoresha 2 × 2, 3 × 3,….
3. Ubugari bwa PCB ubugari ≤260mm (umurongo wa SIEMENS) cyangwa 00300mm (umurongo wa FUJI);niba gutanga byikora bisabwa, ubugari bwa PCB ubugari × uburebure125mm × 180mm.
4. Buri kibaho gito muri puzzle ya PCB kigomba kuba gifite nibura imyobo itatu ihagaze, 3 ≤ aperture ≤ 6 mm, insinga cyangwa gutema ntibyemewe muri mm 1 yumwobo uhagaze.
5. Intera yo hagati hagati yamasahani mato igenzurwa hagati ya 75mm ~ 145mm.
6. Mugihe ushizeho aho uhagaze, mubisanzwe usige ahantu hatagurishijwe 1.5mm nini kuruta aho uhagaze.
7. Ntihakagombye kubaho ibikoresho binini cyangwa ibikoresho bisohoka hafi yihuza hagati yikadiri yinyuma ya puzzle ninyuma yimbere yimbere, no hagati yikibaho gito n'ikibaho gito, kandi hagomba kuba hejuru ya 0.5mm yumwanya hagati ya mpande zibigize na PCB Kugirango umenye neza ko igikoresho cyo gukata gikora bisanzwe.
8. Imyobo ine yimyanya irakinguwe kumpande enye zurwego rwinyuma rwikibaho, kandi umwobo wa diameter ni 4mm ± 0.01mm;imbaraga z'umwobo zigomba kuba ziciriritse kugirango zemeze ko zitavunika mugihe cyo hejuru no hepfo..
9. Ibimenyetso bifatika bikoreshwa muburyo bwa PCB hamwe nibikoresho byiza bihagaze.Ihame, QFPs ifite ikibanza kiri munsi ya 0,65mm igomba gushyirwa kumwanya wabo wa diagonal;Ibimenyetso byerekana ibimenyetso bikoreshwa mugushiraho imbaho zumukobwa PCB zigomba guhuzwa Koresha, shyira muburyo bugaragara kubintu byerekana.
10.Ibice binini bigomba kugira imyanya ihagaze cyangwa imyobo ihagaze, yibanda kuri I / O Imigaragarire, mikoro, interineti ya bateri, micro switch, interineti ya terefone, moteri, nibindi.
