Mu miterere ya PCB, imiterere y'ibigize ibice ni ngombwa, bigena urwego rwiza kandi rwiza rw'ubuyobozi n'uburebure n'ubwinshi bw'insinga zacapwe, kandi ifite ingaruka runaka mu kwizerwa kw'imashini yose.
Ikibaho cyiza cyumuzunguruko, usibye gusohoza ihame ryimikorere, ariko nanone gutekereza EMI, ESC, ESD (ubunyangamugayo bwa electrostatike), ariko no gusuzuma imiterere yubushishozi, ibibazo byinshi bya Chip Ubushyuhe bwa Chip.
Ibisabwa muri rusange PCB Ibisabwa
1, soma inyandiko isobanura ibishushanyo, yujuje imiterere yihariye, module idasanzwe nibindi bisabwa kumiterere.
2, shiraho imiterere ya grid yerekeza kuri 25mil, irashobora guhuzwa ningingo ya gride, spacing ingana; Uburyo bwo guhuza bunini mbere ya Gito (Ibikoresho binini n'ibikoresho binini bihujwe mbere), kandi uburyo bwo guhuza ni ikigo, nkuko bigaragara mu ishusho ikurikira
3, Hura uburebure bwakarere kibujijwe, imiterere nuburyo bwihariye bwibikoresho, ibisabwa by'akarere bibujijwe.
① Igishushanyo 1 (Ibumoso) hepfo: Uburebure butanga ibisabwa, byashyizweho ikimenyetso neza mugice cya mashini cyangwa urwego rwibimenyetso, byoroshye kuri cross-chess-chess-chess-chess-chess
.
Imiterere yimiterere nibikoresho byihariye birashobora gukurikiranwa neza na bihuza cyangwa bihuza byimazeyo cyangwa umurongo wikigo cyibice.
4, imiterere igomba kubanza kubanza gukora imiterere, ntukabone ikibaho kugirango utangire imiterere mu buryo butaziguye, mu kibaho cya PCB gushushanya umurongo w'isesengura, hanyuma ushingiye ku isesengura ry'ibimenyetso, hanyuma ushingiye ku isesengura ry'ibimenyetso, hanyuma ushingiye ku isesengura ry'ibimenyetso, hanyuma ushingiye ku isesengura ry'ibimenyetso, hanyuma ushingiye ku isesengura ry'ibimenyetso, hanyuma ushingiye ku isesengura ry'ibimenyetso, hanyuma ushingiye ku isesengura ry'ibimenyetso, hanyuma ushingiye ku isesengura ry'ibimenyetso, hanyuma rishingiye ku isesengura ry'ibimenyetso, hanyuma rishingiye ku isesengura ry'ibimenyetso, hanyuma rishingiye ku isesengura ry'ibimenyetso, hanyuma rishingiye ku isesengura ry'ibimenyetso, hanyuma rishingiye ku isesengura ry'ibimenyetso, hanyuma rishingiye ku isesengura ry'ibimenyetso, hanyuma rishingiye ku isesengura ry'ibimenyetso, hanyuma rishingiye ku isesengura ry'ibimenyetso, hanyuma rishingiye ku isesengura ry'ibimenyetso, hanyuma rishingiye ku isesengura ry'ibimenyetso, hanyuma rishingiye ku isesengura ry'ibimenyetso, hanyuma rishingiye ku isesengura ry'ibimenyetso. Shushanya umurongo wubufasha 40mil, hanyuma usuzume gushyira mu gaciro imiterere hagati ya module na module binyuze mubikorwa byavuzwe haruguru, nkuko bigaragara ku gishushanyo gikurikira.
5, imiterere ikeneye gusuzuma umuyoboro usiga umurongo w'amashanyarazi, ntagomba kuba umugenzacyaha cyane, mu gutegura, kugahuza aho ari
6, ibice byubushyuhe (nkakazi kamashanyarazi, amashanyarazi
7, kugirango uhuze module yoroshye
Ibimenyetso byinshi hamwe nibimenyetso byinshi bitandukanijwe rwose nikimenyetso cyintege nke z'amazi n'amacoke nke. Ibice byinshi-volutge bikozwe mubice byose bitaweho umuringa. Intera ya Creepage hagati yibice bya voltage ndende biragenzurwa hakurikijwe imbonerahamwe isanzwe
Ikimenyetso cya Analog gitandukanijwe nigimenyetso cya digitale hamwe nubugari bwimibare byibuze 20mil, hamwe na analoge na rf cyangwa 'imyandikire cyangwa'
Ikimenyetso kinini cyaciwe nikimenyetso cyo hasi, intera yo gutandukana ni byibuze 3mm, hamwe numuriro wambukiranya ntushobora kwemezwa
Imiterere yibikoresho byingenzi byerekana nka Crystal OSCIllaTor hamwe numushoferi wisaha bigomba kuba kure yimiterere yumurongo wumuzunguruko, ntabwo ari ku nkombe y'inama y'ubutaka, atari ku nkombe y'Inama y'Ubutegetsi, kandi byibuze 10mm kure y'inama y'ubutegetsi. Arkstal na Crystal OSCortor igomba gushyirwa hafi ya chip, ishyirwa murwego rumwe, ntugashyiremo umwobo, kandi ukibika umwanya wubutaka
Imiterere imwe Umuzunguruko werekana "ibinyabuzima" imiterere isanzwe (gukoresha neza module imwe) kugirango uhuze ibishya byikimenyetso
Nyuma yo gushushanya kwa PCB, tugomba gukora isesengura no kugenzura kugirango umusaruro woroshye.
