Mavuto ndi Mayankho a Kuboola PCB Mofulumira Kwambiri: Kupewa kwa ICD & Kukonza Zida

Popeza zipangizo zothamanga kwambiri zikuchulukirachulukira mu njira zolumikizirana za 5G, zamagetsi zamagalimoto, komanso makompyuta ogwira ntchito bwino, opanga ma PCB akukumana ndi kufunikira kwakukulu kwa kuboola molondola, kugwira ntchito bwino, komanso kudalirika. Makhalidwe apadera a zipangizo zothamanga kwambiri—kutayika kochepa kwa ma transmission, kukana kutentha kwambiri, komanso mphamvu ya makina—zimawonjezera kwambiri magwiridwe antchito a PCB komanso zimayambitsa mavuto akulu pa njira zoboola. Pakati pa izi, ICD (Inner Connection Defects) yakhala chinthu chofunikira kwambiri chomwe chimakhudza kukolola ndi kudalirika kwa PCB.

Mavuto Ofunika Kwambiri Pakuboola PCB Mofulumira Kwambiri

• Zolakwika za ICD: Pa nthawi yosonkhanitsa SMT ndi kutentha kwambiri, kulekanitsidwa kwa utomoni kapena ming'alu kungachitike, zomwe zimapangitsa kuti kulumikizana kwa mkati mwa chipindacho kusayende bwino.
• Moyo Wochepa wa Drill Bit: Kukangana kwakukulu ndi kupsinjika kwa kutentha panthawi yobowola kumathandizira kuwonongeka kwa zida, zomwe zimachepetsa moyo wa bowola ndi zoposa 50%.
• Kugwiritsa Ntchito Mochepa: Ma bowola wamba amafunika kuchepetsa liwiro loposa 20% pokonza zinthu zothamanga kwambiri, zomwe zimachepetsa ntchito yonse.

Kapangidwe ka Drill Bit ndi Kukonza Zophimba

• Kapangidwe ka Drill Bit: Kafukufuku akusonyeza kuti ma USF double-edge single-flute drills ndi ma SHC-coated drills amapereka ntchito yabwino kwambiri pakuboola zinthu mwachangu kwambiri. Kapangidwe ka USF kamathandiza kuchepetsa mapangidwe a ICD, pomwe ma SHC coverings amawonjezera kukana kuwonongeka ndi moyo wa zida.
• Ubwino wa Kuphimba: Poyerekeza ndi zobowola wamba, zida zophimbidwa ndi SHC zimawonjezera moyo wa zida ndi zoposa 30% pomwe zimasunga mabowo abwino nthawi zonse, zomwe zimapangitsa kuti zikhale zoyenera kupanga ma PCB amphamvu komanso othamanga kwambiri.

Kukonza Ma Parameter a Njira

Kuyerekeza kwa mayeso kukuwonetsa kuti:

• Kusintha bwino kwa kuchuluka kwa chakudya ndi liwiro lodula kumachepetsa kwambiri kupangika kwa ma burr ndi kuwonongeka kwa makoma a mabowo.
• Pa ma substrates othamanga kwambiri a 0.25 mm, ma drill okhala ndi SHC adasunga khalidwe lokhazikika kwa ma strips opitilira 600, pomwe ma drill wamba adawonongeka kwambiri atagunda ma strips 400.

Pofuna kuthana ndi mavuto okhudzana ndi kuboola PCB mwachangu, kapangidwe kabwino ka kuboola, ukadaulo wapamwamba wokutira, ndi magawo okonzedwa bwino a njira ndizofunikira kwambiri. Monga opanga PCB ndi PCBA akatswiri, sitimangopereka luso loboola bwino komanso timapereka njira zodalirika komanso zogwira mtima zokonzera njira zomwe zikugwirizana ndi zosowa za makasitomala athu.
