pcb ee xirfad guddi

1. Jirka dibadda (dhinaca isku dhufashada) ee jigsaw PCB waa in uu qaataa nashqad xidhan oo loop ah si loo hubiyo in jigsawda PCB-ga aan la habayn ka dib marka lagu hagaajiyo qalabka;

2. PCB ballac ≤260mm (line SIEMENS) ama ≤300mm (line FUJI); haddii si toos ah loo baahan yahay, guddiga PCB width × dhererka ≤125 mm × 180 mm;

3. Qaabka PCB jigsaw waa inuu ahaadaa mid u dhow sida ugu macquulsan afargeeska. Waxaa lagu talinayaa in la isticmaalo 2×2, 3×3…

4. Masaafada u dhaxaysa taarikada yaryar waxaa lagu xakameynayaa inta u dhaxaysa 75 mm iyo 145 mm;

5. Markaad dejinayso barta meelaynta tixraaca, inta badan ka tag aag aan iska caabin ahayn oo 1.5 mm ka weyn oo ku wareegsan barta meelaynta;

 

6. Waa in aanay jirin aalado waaweyn ama kuwa soo baxaya oo u dhow halka ay isku xidhidhayaan xayndaabka sare ee jigsawda iyo looxa yar ee gudaha, iyo looxa yar iyo looxa yar, waana in ay jiraan wax ka badan 0.5mm oo u dhexeeya qaybaha iyo cidhifka PCB-ga Si loo hubiyo hawlgalka caadiga ah ee qalabka goynta;

7. Afar godood oo meeleyn ah ayaa lagu sameeyay afarta geesood ee qaabka jigjiga, oo leh dhexroor 4mm ± 0.01mm; xoogga godadka waa in uu ahaado mid dhexdhexaad ah si loo hubiyo in aysan jebin doonin inta lagu jiro looxyada sare iyo hoose; saxnaanta dhexroorka daloolka iyo booska waa inuu ahaadaa mid sare, darbiga daloolkuna waa inuu noqdaa mid siman oo aan lahayn burrs;

8. Loox kasta oo yar oo ka mid ah guddiga PCB waa inuu lahaadaa ugu yaraan saddex godad, 3≤aperture≤6 mm, lamana oggola wax fiilo ama balastar ah gudaha 1mm godka meelaynta cidhifka;

9. Calaamadaha tixraaca ee loo isticmaalo meelaynta PCB-ga oo dhan iyo meelaynta aaladaha garaafyada. Mabda 'ahaan, QFP oo leh kala fogaansho ka yar 0.65mm waa in lagu dejiyaa booskeeda gees; Calaamadaha tixraaca meelaynta ee loo isticmaalo looxa inanta PCB waa in la isku lammaaniyaa Isticmaal, oo lagu habeeyey gees ka soo horjeeda qaybta meelaynta;

10. Qaybaha waaweyni waa inay lahaadaan boosaska meelaynta ama godadka meelaynta, sida I/O interface, makarafoon, interface batari, furaha micro, interface-ephone interface, motor, iwm.
