1. Guddiga PCB qaabku waa inuu ahaadaa mid u dhow afargeeslaha suurtogalka ah, 2 & TImes ayaa lagula talinayaa; 2, 3, & TImes; 3, … Isqurxin; Laakiin ha samayn guddiga Yin iyo Yang

2.BBCB width guddiga ≤260mm (line SIEMENS) ama ≤300mm (line FUJI); Haddii qaybinta otomaatiga ah loo baahan yahay, ballaarka guddiga PCB & TImes; Dhererka 125 mm ama ka yar & TImes; 180mm.

3. Jidadka dibadda (geeska xajinta) ee guddiga PCB waa inuu qaataa naqshad xidhxidhan si loo hubiyo in guddiga PCB uusan u xuub-siibmin ka dib marka lagu hagaajiyo qalabka

4. Masaafada u dhexaysa taargooyinka yaryar waa in la xakameeyaa inta u dhaxaysa 75mm iyo 145mm

5. Waa inaanay jirin qalab weyn ama aalad la dheereeyey meel u dhow meesha isku xidhka ee u dhexeeya jir -ka dibadda iyo saxanka yar ee gudaha ah, iyo inta u dhexaysa saxanka yar iyo saxanka yar, iyo cidhifka qaybaha iyo looxa PCB -ga waa in loo daayaa meel ka weyn 0.5mm si loo hubiyo hawlgalka caadiga ah ee qalabka goynta

6. 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; Furitaanka iyo saxsanaanta booska waa inay ahaataa mid sare, darbiga daloolka oo siman oo aan buur lahayn

7. Boodh kasta oo yar oo ku jira guddiga PCB waa inuu lahaadaa ugu yaraan saddex godad oo meelaynta, 3≤ aperture ≤6mm, godadka meelaynta geesku 1mm gudahood looma oggola inay silig galaan

8. Calaamadda tixraaca ee PCB-ga oo dhan meeleynta guddiga iyo meeleynta aaladda wanaagsan waa in lagu dhejiyaa booska dadban ee QFP oo leh garoon ka hooseeya 0.65mm mabda ‘ahaan; Meeleynta calaamadaha datum-ka ee guddiyada PCB waa in loo adeegsadaa laba-labo waxaana lagu diyaariyey xarriiqda walxaha meelaynta.

9. Qaybaha waaweyn waa inay lahaadaan boosaska meelaynta ama daloollada meelaynta, sida I/O interface, makarafoon, is -beddelka batteriga, beddelka micro, is -dhex -gelinta dhagaha, mootada, iwm.

10. Markaad dejinayso bar -tilmaameedka tixraaca, aag alxanka furan oo ka weyn 1.5mm ayaa inta badan la dhigaa agagaarka barta barroosinka
