Yeyiphi imiba ekufuneka inikwe ingqwalasela kwi PCB iipads?

I-Pad luhlobo lomngxuma, uyilo lwephedi kufuneka lunikele ingqalelo kule miba ilandelayo.

1. Ubukhulu kunye nobukhulu bomngxuma ongaphakathi wephedi: Umngxunya wangaphakathi wephedi ngokubanzi awukho ngaphantsi kwe-0.6mm, kuba akukho lula ukuqhubekeka xa umngxunya ungaphantsi kwe-0.6mm. Ngokwesiqhelo, ubukhulu bepini yentsimbi kunye ne-0.2mm isetyenziswa njengendawo engaphakathi emngxunyeni wephedi. Ukuba ubukhulu bepini yensimbi yokuxhathisa yi-0.5mm, ububanzi bomngxunya ongaphakathi wephedi yi-0.7mm, kwaye ububanzi bephedi buxhomekeke kububanzi bomngxunya ongaphakathi. Idayamitha yomngxuma / ipad ububanzi ngokuqhelekileyo: 0.4 / 1.5; Ngo-0.5/1.5;Ngo-0.6/2; Ngo-0.8/2.5; Ngo-1.0/3.0; Ngo-1.2/3.5; 1.6/4. Xa ububanzi bepadi buyi-1.5 mm, ukuze kwandiswe amandla okuhlutha ipadi, ubude obungekho ngaphantsi kwe-1.5 mm, ububanzi be-1.5 mm ubude bephedi setyhula bunokusetyenziswa, olu hlobo lwephedi luxhaphake kakhulu. ipadi yephini yesekethe edibeneyo. Ngobubanzi beepads ngaphaya kobubanzi betafile engentla, le fomyula ilandelayo ingasetyenziselwa ukukhetha: umngxuma onobubanzi obungaphantsi kwe-0.4mm: D / D = 1.5-3; Imingxuma enobubanzi obungaphezulu kwe-2rran: D/ D =1.5-2 (apho: D yidayamitha yeepadi kunye no-D ububanzi bemingxuma engaphakathi)

2. Umgama phakathi komda womngxuma wangaphakathi wepadi kunye nomda webhodi eprintiweyo kufuneka ube mkhulu kune-1 mm, ukwenzela ukuba ugweme i-defect of pad ngexesha lokucubungula.

3. Xa ucingo oluxhunyiwe kunye ne-pad luncinci, ukudibanisa phakathi kwe-pad kunye nocingo kuklanyelwe kwisimo se-droplet, okungekho lula ukukhupha i-pad, kwaye ucingo kunye ne-pad akulula ukuqhawula.

4. Iipads ezikufutshane ukuphepha kwi-Angle ebukhali okanye indawo enkulu ye-foil yobhedu. I-Angle ebukhali iya kubangela ubunzima bokuntywila kwamaza, kwaye kukho ingozi yokubopha ibhulorho, indawo enkulu yefoyile yobhedu ngenxa yokutshatyalaliswa kobushushu obugqithisileyo kuya kukhokelela kubunzima bokuwelda.
