I-PCB kwisakhono sepaneli

1. Isakhelo sangaphandle (icala elisecaleni) le-jigsaw i-jigsaw kufuneka yamkele uyilo oluvaliweyo loyilo lokuqinisekisa ukuba i-PCB jigsaw ayiyi kutshitshiswa emva kokuba ilungiselelwe umjikelo;

I-2. I-PCB yePCB ububanzi be-≤260mm (umgca we-Niemens) okanye ≤300mm (umgca we-fuji); Ukuba ukwenziwa kwezinto ezisetyenziswayo ngokuzenzekelayo kuyafuneka, ububanzi bePCB ububanzi be-PCB

I-3. Ubume bejigsaw jigsaw kufuneka busondele kangangoko kunokwenzeka kwisikwere. Kucetyiswa ukuba usebenzise 2 × 2, 3 × 3 ...

I-4. Umgama ophakathi phakathi kweepleyiti ezincinci zilawulwa phakathi kwe-75 mm kunye ne-145 mm;

5. Xa useta inqaku lendawo yokubeka ireferensi, ihlala ishiya indawo engaphili i-1.5 mm enkulu kunokuba ijikeleze indawo yokubeka;

 

6. Akufuneki kubekho zixhobo ezinkulu okanye izixhobo zokuphuma kufutshane nendawo yoqhagamshelo phakathi kwe-jigsaw kunye neBhodi encinci engaphakathi, kwaye kufanele kubekho indawo encinci yePCB ukuqinisekisa ukusebenza kwesixhobo esiqhelekileyo;

7. Imingxunya emine yendawo yenziwa kwiikona ezine zesakhelo se-jigsaw, nge-4mm ± 0.01mm; Amandla emingxunya kufuneka abe ngokumodareyitha ukuqinisekisa ukuba abayi kuqhekeka ngexesha leebhodi eziphezulu nangaphantsi; Ukuchaneka kwe-Hole Deameter kunye neSikhundla kufuneka kuphakame, kwaye udonga lomngxunya kufuneka lugudile kwaye likhululwe kukungcwaba;

8. Ibhodi nganye encinci kwiphaneli ye-PCB kufuneka ibenemingxunya emithathu ubuncinci, i-3 ≤iaperture≤6 mm, kwaye akukho ntambo okanye i-patch ivunyelwe ngaphakathi komngxunya wokubeka umphetho;

9. Iimbovane zezaziso ezisetyenziselwa ukuma kwindawo yonke ye-PCB kunye nokuma kwezixhobo zepitch ezihle. Kwimiselo, i-QFP enendawo engaphantsi kwe-0.65mm kufuneka isethwe kwindawo yayo yokunyanzelwa; Iimpawu zezaziso zokubhengeza ezisetyenziselwa iBhodi yentombi yePCB ye-PCB kufuneka isetyenziswe isetyenzisiwe, icwangciswe kwikona echaseneyo yendawo yokubeka;

I-10. Izinto ezinkulu kufuneka zibe nezikhundla ezikhoyo okanye zibeka imingxunya, njenge-I / O, i-microphone, i-microphone, i-ractone yetekisi, i-switch ye-Microw, i-Idemon, njl.
