Guud ahaan, wax soo saarka PCB waxaa loo yaqaan Panelization si loo kordhiyo hufnaanta khadka wax soo saarka SMT. Waa maxay faahfaahinta la fiirinayo Golaha PCB? Aynu eegno.

1. Qaab-dhismeedka guddiga PCB (geeska xajinaya) waa inuu qaataa naqshad xidhxidhan si loo hubiyo in guddiga PCB uusan u xuub-siibmin ka dib marka lagu dhejiyo qalabka;

2, qaabka guddiga PCB sida ugu dhow ee ugu dhow labajibaaran, lagu taliyay 2 × 2, 3 × 3 …… Jigsaw, laakiin aan gelin guddonka Yin iyo Yang;

3, baaxadda guddiga PCB ≤260mm (SIEMENS line) ama ≤300mm (line FUJI); Haddii qaybinta otomaatiga ah loo baahan yahay, ballac × dhererka guddiga PCB ≤125mm × 180mm;

4, boodh kasta oo yar oo ka mid ah looxa PCB waa inuu lahaadaa ugu yaraan saddex godad oo meelaynta, 3≤ aperture ≤6 mm, godka meelaynta geeska 1mm gudaheeda looma oggola in la xadhko ama la dhejiyo;

5, masaafada u dhexaysa kontaroolka saxanka yar ee u dhexeeya 75mm ~ 145mm;

6, marka la dejinayo bar -tilmaameedka tixraaca, badiyaa barta dejinta agagaarka aagga alxanka furan 1.5mm ka weyn;

7. Waa inaanay jirin qalab weyn ama aalad la dheereeyey meel u dhow meesha isku xirnaanta ee u dhexeysa shaxda dibadda iyo saxanka yar ee gudaha, iyo cidhifka qaybaha iyo guddiga PCB waa inay lahaadaan meel ka weyn 0.5mm si loo hubiyo hawlgalka caadiga ah ee qalab goynta;

8. Afar dalool oo meelaynta ayaa laga furaa afarta gees ee looxyada sare ee looxyada, oo leh daloolada 4mm ± 0.01mm; Xoogga daloolku waa inuu ahaadaa mid dhexdhexaad ah si loo hubiyo inuusan ka jabi doonin habka taargooyinka sare iyo hoose; Daloolka iyo saxsanaanta booska si ay u noqoto mid sare, oo derbi god leh oo aan buur lahayn;

9. Mabda ‘ahaan, QFP oo leh dherar ka yar 0.65mm waa in lagu dhejiyaa booska dadabbe ee calaamadda tixraaca ee meelaynta guddiga PCB oo dhan iyo meelaynta aaladda wanaagsan; Calaamadaha xogta meeleynta ee guddiyada PCB-ga waa in loo adeegsadaa laba-labo waxaana lagu diyaariyey xarriiqda qaybaha meelaynta;

10, qaybaha waaweyn waa inay lahaadaan tiirar meelaynta ama daloollada meelaynta, sida isuduwaha I/O, makarafoon, is -beddelka batteriga, beddelashada micro, interface headphone, motor, iwm.
