Feem ntau, PCB ntau lawm hu ua Panelization txhawm rau ua kom muaj txiaj ntsig ntawm SMT cov kab ntau lawm. Cov ntsiab lus dab tsi yuav tsum tau them nyiaj mloog rau hauv PCB sib dhos? Cia wb mus saib nws.

1. PCB pawg thawj coj (clamping ntug) yuav tsum tau txais kev kaw lub voj tsim kom ntseeg tau tias PCB pawg thawj coj yuav tsis deformed tom qab nws tau teeb tsa ntawm lub teeb;

2, PCB pawg thawj coj saib kom ze li sai tau rau lub xwmfab, pom zoo 2 × 2, 3 × 3 …… Jigsaw, tab sis tsis nkag rau hauv Yin thiab Yang board;

3, PCB pawg thawj coj saib dav ≤260mm (SIEMENS kab) lossis ≤300mm (FUJI kab); Yog tias xav tau kev faib khoom tsis siv neeg, dav × ntev ntawm PCB pawg thawj coj saib ≤125mm × 180mm;

4, txhua lub rooj tsav xwm me me hauv PCB pawg thawj coj yuav tsum muaj tsawg kawg peb qhov tso rau qhov, 3≤ lub qhov taub ≤6 hli, ntug qhov tso rau hauv 1 hli tsis pub xaim lossis thaj;

5, qhov nruab nrab nruab nrab ntawm cov phaj me me tswj ntawm 75mm ~ 145mm;

6, thaum teeb tsa qhov chaw teeb tsa siv, feem ntau nyob hauv qhov chaw teeb tsa ib puag ncig qhib thaj tsam 1.5 hli loj dua nws;

7. Yuav tsum tsis muaj lub cuab yeej loj lossis cov cuab yeej txuas ntxiv nyob ze ntawm qhov txuas ntawm lub thav duab sab nrauv thiab sab hauv phaj me me, thiab ntug ntawm cov khoom sib dhos thiab PCB pawg thawj coj yuav tsum muaj qhov chaw ntau dua 0.5 hli kom ntseeg tau tias kev ua haujlwm ib txwm muaj tej cuab yeej;

8. Plaub qhov chaw tso tau qhib ntawm plaub fab ntawm lub thav duab sab nrauv ntawm lub rooj tsavxwm, nrog lub qhov tob ntawm 4mm ± 0.01mm; Lub zog ntawm lub qhov yuav tsum muaj qhov nruab nrab kom ntseeg tau tias nws yuav tsis tawg hauv cov txheej txheem ntawm cov phaj sab saud thiab qis; Aperture thiab txoj hauj lwm raug kom siab, du qhov phab ntsa tsis muaj burr;

9. Hauv txoj ntsiab cai, QFP nrog qhov sib nrug tsawg dua 0.65mm yuav tsum tau teeb tsa hauv kab pheeb ces kaum ntawm cov cim siv rau PCB tag nrho pawg thawj coj tso rau hauv thiab rau cov cuab yeej ua haujlwm zoo; Cov cim cim qhov chaw rau PCB pawg thawj coj yuav tsum tau siv ua khub thiab npaj rau ntawm kab pheeb ces kaum ntawm cov ntsiab lus muab tso rau;

10, cov khoom loj yuav tsum muaj cov kab sib dhos los yog qhov chaw, xws li I/O interface, microphone, roj teeb interface, hloov micro, lub mloog pob ntseg sib txuas, lub cev muaj zog, thiab lwm yam.
