H\u0131zl\u0131 cevap:<\/strong> For practical formulation work, photoinitiator screening starts with the light source and film build, then checks yellowing, adhesion, and cure completeness under real production conditions.<\/p>\n

Yap\u0131lan bak\u0131r devre \u00fczerindeki bask\u0131l\u0131 devre kart\u0131, lehim ba\u011flant\u0131lar\u0131na ek olarak kart y\u00fczeyi, kart\u0131n geri kalan\u0131n\u0131n dalga lehimleme yoluyla kart\u0131n sadece lehimdeki lehim ba\u011flant\u0131lar\u0131n\u0131 sa\u011flamak i\u00e7in bir lehim direnci tabakas\u0131n\u0131 kaplamas\u0131 gerekir, \u00e7izgi grafik par\u00e7as\u0131n\u0131n geri kalan\u0131 lehim ile lekelenmez. Lehim direnci \u00fczerindeki serigrafi y\u00f6nteminde lehim direnci m\u00fcrekkebinde kullan\u0131l\u0131r. Farkl\u0131 k\u00fcrleme y\u00f6ntemleri nedeniyle, lehim diren\u00e7li m\u00fcrekkebin ayr\u0131ca iki t\u00fcr \u0131s\u0131 ayarl\u0131 ve \u0131\u015f\u0131k ayarl\u0131, \u015fu anda esas olarak \u0131\u015f\u0131k ayarl\u0131 lehim diren\u00e7li m\u00fcrekkebi vard\u0131r. Lehim diren\u00e7li grafikler ayr\u0131ca k\u00fcrlendikten sonra ekran s\u0131z\u0131nt\u0131s\u0131 bask\u0131s\u0131 yoluyla m\u00fcrekkep taraf\u0131ndan olu\u015fturulur, \u00e7\u00fcnk\u00fc bask\u0131l\u0131 devre kart\u0131 \u00fczerinde kal\u0131c\u0131 bir kaplamad\u0131r, bu nedenle m\u00fckemmel elektriksel \u00f6zelliklere ve fiziksel mekanik \u00f6zelliklere sahip olmak, ayn\u0131 zamanda 260 \u2103 (askeri \u00fcr\u00fcnler 288 \u2103'ye dayanacak \u015fekilde) y\u00fcksek s\u0131cakl\u0131k.<\/p>\n

UV lehim diren\u00e7li m\u00fcrekkep oligomeri esas olarak iyi \u0131s\u0131 direnci, iyi yal\u0131t\u0131m, bisfenol A - epoksi akrilat, fenolik epoksi akrilat ve poli\u00fcretan akrilat gibi bak\u0131r re\u00e7ine ile iyi yap\u0131\u015fma se\u00e7er, \u015fu anda yayg\u0131n olarak kullan\u0131lan fenolik epoksi akrilatt\u0131r. Reaktif seyreltici, monofonksiyonel hidroksil esterli polifonksiyonel akrilatt\u0131r, fotoba\u015flat\u0131c\u0131 esas olarak 907 veya DETX kullan\u0131l\u0131r. \u00f6nceki pigment esas olarak ftalosiyanin ye\u015filidir, ancak \u015fimdi renklendirici pigmentin siyah, alt\u0131n ve di\u011fer se\u00e7enekleri vard\u0131r ve \u0131s\u0131 direncini art\u0131rmak ve hacim b\u00fcz\u00fclmesini azaltmak i\u00e7in yararl\u0131 olan daha fazla dolgu maddesi ekleyebilir. M\u00fcrekkep ve bak\u0131r\u0131n yap\u0131\u015fmas\u0131n\u0131 iyile\u015ftirmek i\u00e7in, fosfor metakrilat mono- veya di-ester gibi k\u00fc\u00e7\u00fck bir yap\u0131\u015fma artt\u0131r\u0131c\u0131 da eklemeniz gerekir.<\/p>\n

UV lehim diren\u00e7 m\u00fcrekkepleri haz\u0131rlan\u0131rken, fotoba\u015flat\u0131c\u0131lar\u0131n dikkatle se\u00e7ilmesi gerekir. Yukar\u0131da bahsedilen 907 ve DETX'e ek olarak, yayg\u0131n olarak kullan\u0131lan 784 ve 369 bu sistem i\u00e7in uygundur.<\/p>\n
