Inzira yihariye ya PCB yumuzunguruko

Gahunda yo gukora PCB yubuyobozi irashobora kugabanwa mubice cumi na bibiri bikurikira. Buri nzira isaba uburyo butandukanye bwo gukora. Twabibutsa ko inzira yimbaho ​​yimbaho ​​zifite imiterere itandukanye. Inzira ikurikira nigikorwa cyuzuye cya PCB nyinshi. inzira igenda;

Ubwa mbere. Imbere; cyane mugukora ibice byimbere byumuzunguruko wa PCB; inzira yo kubyaza umusaruro ni:
1. Gukata ikibaho: gukata substrate ya PCB mubunini bw'umusaruro;
2. Mbere yo kuvura: sukura hejuru ya PCB substrate hanyuma ukureho umwanda
3. Laminating firime: andika firime yumye hejuru yubutaka bwa PCB kugirango witegure kohereza amashusho nyuma;
4. Kumurika: Koresha ibikoresho byerekana kugirango ugaragaze substrate ifatanye na substrate yumucyo ultraviolet, kugirango wohereze ishusho ya substrate kuri firime yumye;
5.
Icya kabiri. Igenzura ry'imbere; cyane mugupima no gusana imirongo yinama;
1.
2.
3. Umugozi winyongera: Kugurisha insinga ya zahabu ku cyuho cyangwa kwiheba kugirango wirinde amashanyarazi;
Icya gatatu. Kanda; nkuko izina ribivuga, imbaho ​​nyinshi zimbere zikanda mukibaho kimwe;
.
2. Kuzunguruka: Kata PP mumpapuro ntoya nubunini busanzwe kugirango ikibaho cyimbere hamwe na PP bihuye hamwe
3. Gupfundikanya no gukanda, kurasa, gukata gong, kuruhande;
Icya kane. Gucukura: ukurikije ibyifuzo byabakiriya, koresha imashini yo gucukura kugirango ucukure umwobo ufite diametero nubunini butandukanye kurubaho, kugirango umwobo uri hagati yimbaho ​​ushobora gukoreshwa mugutunganya ibyuma byacometse, kandi birashobora no gufasha inama gutandukana. ubushyuhe;

Icya gatanu, umuringa wibanze; umuringa usize umwobo wacukuwe ku kibaho cyo hanze, ku buryo imirongo ya buri cyiciro cyibibaho ikorwa;
1.
2. Umurongo wo gukuraho kole: kura ibisigazwa bya kole mu mwobo; murwego rwo kongera gufatira mugihe micro-etching;
3.
Icya gatandatu, igice cyo hanze; urwego rwinyuma rusa nkurwo rugendo rwimbere rwintambwe yambere, kandi intego yarwo nukworohereza inzira yo gukurikirana kugirango izenguruke;
1.
2. Laminating firime: andika firime yumye hejuru yubutaka bwa PCB kugirango witegure kohereza amashusho nyuma;
3. Kumurika: kurabagirana nurumuri rwa UV kugirango firime yumye kurubaho igizwe na polymerized kandi idafite polimerime;
4. Iterambere: gusesa firime yumye itigeze iba polymerime mugihe cyo kwerekana, hasigara icyuho;
Icya karindwi, umuringa wa kabiri no gutobora; icyuma cya kabiri cy'umuringa, gutobora;
1. icyarimwe, ongera wongere ubworoherane nubunini bwumuringa, hanyuma unyure mumabati kugirango urinde ubusugire bwumuzingi nu mwobo mugihe cyo kurira;
2.

Umunani, kurwanya ibicuruzwa: birashobora kurinda ikibaho no gukumira okiside nibindi bintu;
1. Kwitegura: gutoragura, gukaraba ultrasonic hamwe nubundi buryo bwo gukuraho okiside ku kibaho no kongera ubukana bw’umuringa;
2.
3. Mbere yo guteka: gukama umusemburo mubagurisha birwanya wino, kandi icyarimwe ugakomera wino kugirango ugaragare;
4. Kumenyekanisha: Gukiza uwagurishije kurwanya wino ukoresheje imirasire yumucyo UV, no gukora polymer ndende ikoresheje Photopolymerisation;
5. Iterambere: kuvanaho sodium ya karubone muri wino idafite polimerize;
6. Nyuma yo guteka: gukomera byuzuye wino;
Icyenda, inyandiko; inyandiko yanditse;
1. Gutoragura: Sukura hejuru yikibaho, ukureho okiside yo hejuru kugirango ushimangire guhuza wino yo gucapa;
2. Inyandiko: inyandiko yanditse, yoroshye kubikorwa byo gusudira nyuma;
Icya cumi, kuvura hejuru ya OSP; uruhande rw'isahani y'umuringa yambaye ubusa igomba gusudira isizwe kugirango ikore firime ngenga kugirango irinde ingese na okiside;
Icya cumi na rimwe, gushinga; imiterere yinama isabwa numukiriya ikorwa, ikorohereza umukiriya gukora SMT gushyira no guteranya;
Icya cumi na kabiri, ikizamini cyo kuguruka; gerageza umuzenguruko wibibaho kugirango wirinde gusohoka kwakanya gato k'umuzunguruko;
Cumi na gatatu, FQC; ubugenzuzi bwa nyuma, icyitegererezo no kugenzura byuzuye nyuma yo kurangiza inzira zose;
Icya cumi na kane, gupakira no hanze yububiko; vacuum-gupakira ikibaho cya PCB cyuzuye, gupakira no kohereza, hanyuma urangize gutanga;
