Si loo fududeeyo wax-soo-saarka iyo soo-saarka, PCBpcb guddiga wareegga wareegga guud ahaan waa inay naqshadeeyaan barta Mark, V-groove, iyo cidhifka farsamaynta.
Naqshadaynta muuqaalka PCB
1. Qaabka (cidhifka isku dhufashada) ee habka kala-baxa PCB waa in uu qaataa nidaamka naqshadaynta kontoroolka-loop-ka-xiran si loo hubiyo in habka kabidda PCB-ga aanu si sahal ah u habayn ka dib marka lagu hagaajiyo qalabka.
2. Wadarta guud ee habka kala-baxa PCB waa ≤260Mm (line SIEMENS) ama ≤300mm (line FUJI); Haddii loo baahan yahay dhejis toos ah, wadarta guud ee habka kala-baxa PCB waa 125mm × 180mm.
3. Naqshadeynta muuqaalka habka fuulista PCB waxay u dhowdahay afargeeska intii suurtagal ah, waxaana si adag loogu talinayaa in la isticmaalo 2 × 2, 3 × 3, ... iyo habka boarding; laakiin looma baahna in la higgaadiyo looxyada togan iyo kuwa taban;
pcbV- gooyay
1. Ka dib marka la furo V-cut, dhumucda soo hadhay ee X waa in ay ahaataa (1/4～1/3) dhumucda saxanka L, laakiin dhumucda ugu yar ee X waa in ay ahaataa ≥0.4mm. Xayiraado ayaa diyaar u ah looxyada leh culeyska culus, iyo xad hoose ayaa diyaar u ah looxyada leh culeysyo fudud.
2. Barokaca S ee nabarka bidix iyo midig ee V-cut waa inuu ka yar yahay 0 mm; Sababtoo ah xadka dhumucda ugu yar ee macquulka ah, habka V-cut splicing kuma habboona guddiga dhumucdiisuna waxay ka yar tahay 1.3mm.
Calaamadee barta
1. Markaad dejinayso barta xulashada caadiga ah, guud ahaan bannee meel aan cidhiidhi ahayn oo 1.5 mm ka weyn hareeraha barta xulashada.
2. Loo isticmaalo in lagu caawiyo muraayadaha elektiroonigga ah ee mashiinka meelaynta smt si sax ah loo helo geeska sare ee guddiga PCB oo leh qaybo jajab ah. Waxaa jira ugu yaraan laba dhibcood oo cabbir oo kala duwan. Dhibcaha cabbiraadda meelaynta saxda ah ee PCB oo dhan guud ahaan waa hal gabal. Mawqifka qaraabada ah ee geeska sare ee PCB; Dhibcaha cabbiraadda ee meelaynta saxda ah ee muraayadaha korantada ee PCB-ga ee lakabka ah ayaa guud ahaan ku yaal geeska sare ee guddiga wareegga wareegga PCB pcb.
3. Qaybaha QFP (xirmo fidsan laba jibaaran) oo leh kala dheerayn fiilada ≤0.5 mm iyo BGA (xirmo array grid ball) oo leh kala dheerayn kubbadda ≤0.8 mm, si loo hagaajiyo saxnaanta chip-ka, waxaa lagu qeexaa in la dhigo labada geesaha sare ee barta Cabbirka IC.
dhinaca farsamada farsamaynta
1. Xudduudda u dhaxaysa sabuuradda iyo sabuuradda gudaha, noodhka u dhexeeya sabuuradda weyn iyo sabuuradda weyn waa in aanay noqon mid weyn ama ka laadlaadsan, cidhifka aaladda elegtarooniga ah iyo guddiga wareegga PCBpcb waa in ay ka tagaan in ka badan 0.5 mm gudaha gudaha ah. meel bannaan. Si loo hubiyo hawlgalka caadiga ah ee goynta laysarka ee CNC.
godadka meelaynta saxda ah ee looxa
1. Waxaa loo isticmaalaa meelaynta saxda ah ee dhammaan guddiga wareegga PCB ee guddiga wareegga PCBpcb iyo calaamadaha caadiga ah ee meelaynta saxda ah ee qaybaha ganaaxa. Xaaladaha caadiga ah, QFP oo leh dhexda ka yar 0.65mm waa in lagu dhejiyaa geeskeeda sare; Calaamadaha meelaynta saxda ah ee guddiga gabadha PCB ee guddiga waa in lagu dabaqaa labo-labo oo la dhigaa geesaha sare ee qodobada meelaynta saxda ah.
2. Boorarka meelaynta saxda ah ama godadka meelaynta saxda ah waa in loo dhigaa qaybaha waaweyn ee elegtarooniga ah, sida jaakooyinka I/O, makarafoonada, jaakadaha baytariyada dib loo dallaci karo, furayaasha roga, dhagaha dhagaha, matoorada, iwm.
Naqshadeeye PCB-ga wanaagsan waa inuu ku xisaabtamaa walxaha wax-soo-saarka iyo wax-soo-saarka marka uu horumarinayo qorshaha naqshadaynta halxiraalaha si loo hubiyo wax-soo-saarka iyo hab-samaynta habboon, hagaajinta wax-soo-saarka, iyo dhimista kharashyada alaabta.
