IPC-6012, SMB-SMT Iphrintiwe amabhodi wesifunda abe ne-warpage enkulu noma i-twist engu-0.75%, kanti amanye amabhodi ngokuvamile awedluli u-1.5%;i-warpage evumelekile (izinhlangothi ezimbili/izingqimba eziningi) yesitshalo sokuhlanganisa i-elekthronikhi ngokuvamile ingu-0.70 ---0.75%, (ugqinsi oluyi-1.6mm) Eqinisweni, amabhodi amaningi afana namabhodi e-SMB kanye ne-BGA adinga i-warpage engaphansi kuka-0.5%;ezinye izimboni ngisho ngaphansi kuka-0.3%;I-PC-TM-650 2.4.22B

Indlela yokubala ye-warpage = ubude bekhasi le-warpage/ubude bonqenqema olugobile
Ifekthri yebhodi lesifunda sebhethri ikufundisa ukuthi ungavimbela kanjani i-warpage yebhodi lesifunda:

1. Idizayini yobunjiniyela: ilungiselelo le-interlayer prepreg kufanele lihambisane;ibhodi elinezingqimba eziningi kanye ne-prepreg kufanele isebenzise umkhiqizo ofanayo womphakeli;indawo yehluzo ye-C/S yangaphandle kufanele ibe seduze ngangokunokwenzeka, futhi amagridi azimele angasetshenziswa;

2. Ibhodi lokubhaka ngaphambi kokusika
Ngokujwayelekile ama-degree angu-150 amahora angu-6-10, susa umswakama ebhodini, uqhubeke wenze ukwelashwa kwe-resin ngokuphelele, futhi uqede ukucindezeleka ebhodini;ukubhaka ibhodi ngaphambi kokusika, kungakhathaliseki ukuthi ungqimba lwangaphakathi noma izinhlangothi zombili ziyadingeka!

3. Naka isiqondiso se-warp ne-weft yeshidi elilashiwe ngaphambi kokupakisha ibhodi lezendlalelo eziningi:
I-warp ne-weft shrinkage ratio ihlukile.Naka isiqondiso se-warp ne-weft ngaphambi kokusika ishidi le-prepreg;qaphela isiqondiso se-warp ne-weft lapho usika ibhodi eliyinhloko;ngokuvamile i-curring sheet roll isiqondiso isiqondiso se-wap;isiqondiso eside se-laminate ye-copper clad yi-warp direction;Izendlalelo ezingu-10 4OZ Amandla epuleti lethusi eliwugqinsi

4. Laminating obukhulu ukuze kuqedwe ukucindezeleka, ukucindezela okubandayo ngemva kokucindezela ibhodi, nquma ama-burrs;

5. Ibhodi lokubhaka ngaphambi kokumba: ama-degree angu-150 amahora angu-4;

6. Kungcono ukungaxubi ngomshini ipuleti elincane, futhi ukuhlanza amakhemikhali kunconywa;izinto ezikhethekile zisetshenziswa ngesikhathi se-electroplating ukuvimbela ipuleti ukuthi lingagobi futhi ligoqe

7. Ngemva kokufafaza uthayela, zipholisa ngokwemvelo uze ufike ezingeni lokushisa elilingana negumbi lemabula eliyisicaba noma ipuleti lensimbi noma uhlanze ngemva kokupholisa embhedeni ontantayo;
