Nigute ushobora guhuza PCB kugirango byoroshye guterana kwa PCB?

Mu rwego rwo kuzamura umusaruro no kugabanya ikiguzi cy'umusaruro muriInteko ya PCBinzira, ikibaho cyumuzunguruko cyambaye ubusa gikora muburyo bwo gukora, gishobora korohereza uruganda rutunganya PCBA gukora gusudira chip.Ibikurikira bizavuga uburyo rusange hamwe namahame yinama yumuzunguruko.

Ihame ryo guhuza PCB:

1. Ingano yubugari bwibibaho bya PCB ≤ 300mm (umurongo wa Fuji);niba ukeneye gutanga byikora, ubunini bwa PCB bugomba ≤ 125mm (W) × 180mm (L).
2. Imiterere ya PCB igomba kuba hafi ya kare uko bishoboka kwose, kandi igasaba ko ikibaho gikata ari (2 * 2、3 * 3、4 * 4) muri buri kibaho.
3. Ikadiri yo hanze (clamping edge) yinama yumuzunguruko igomba gufata igishushanyo-gifunze kugirango harebwe niba akanama ka PCB katazahinduka nyuma yuko kamaze gushyirwaho.
4. Intera ntoya ya PCB yubuyobozi igomba kugenzurwa muri 75mm ~ 145mm.
5. Ntabwo hazaba ibikoresho binini cyangwa ibikoresho bisohoka hafi yumwanya uhuza hagati yikadiri yinyuma yikibaho cyimbere hamwe nimbaho ​​ntoya imbere, kandi hazaba umwanya urenze 0.5mm hagati yibigize ninkombe yubuyobozi bwa PCB kugeza menya imikorere isanzwe yigikoresho cyo gukata.
6. Ku mfuruka enye z'ikaramu yo hanze ya PCB, hafunguwe imyobo ine ihagaze kandi umwobo wa diameter ni (4mm ± 0.01mm);Imbaraga z'umwobo zigomba kuba ziciriritse kugira ngo zitazacika mu gihe cyo gutwara no gupakurura;Umwobo wa diametre hamwe nukuri neza neza bizaba birebire, kandi umwobo ugomba kuba mwiza.
7. Buri kibaho gito muri PCB kigomba kugira byibuze imyanya itatu ihagaze, 3 ≤ umwobo wa diameter ≤ 6mm, kandi insinga cyangwa SMT ntibyemewe muri 1mm yumwobo uhagaze.
8. Iyo ushyizeho aho uhagaze, umwanya wo gusudira utarwanya 1.5mm kurenza aho uhagaze mubisanzwe ubikwa hafi yumwanya.
9. Ibice binini bigomba guhabwa imyanya ihagaze cyangwa umwobo uhagaze, nka: mikoro, interineti ya bateri, microswitch, interineti yumutwe, moteri, nibindi.

Ubusanzwe PCB ihuza inzira muburyo:

1 、 V-GUCA
V.Ninzira ikunzwe cyane muri iki gihe.

2. Gukubita ibiti
Gukubita bivuga gusya ubusa hagati yamasahani cyangwa imbere yisahani hamwe nimashini yo gusya nkuko bisabwa, bihwanye no gucukura.

3. Ikidodo
Ibi bivuze gukoresha umwobo muto kugirango uhuze ikibaho cya PCB, gisa nkicyatsi kibisi kuri kashe, bityo cyitwa kashe ya kashe.Ihuza rya kashe isaba kugenzura burr hafi yikibaho, icyo ni umwobo muto wa kashe ushobora gukoreshwa kugirango usimbuze umurongo V.
