Daher m\u00fcssen die Teile der Schaltung, die nicht ge\u00e4tzt werden sollen, mit einem Resist gesch\u00fctzt werden. Beim Siebdruck wird eine Resistfarbe verwendet, die je nach Aush\u00e4rtungsmethode entweder selbsttrocknend oder lichth\u00e4rtend ist. Die Resistfarbe wird durch ein Sieb mit einem Resistmuster gedruckt und auf dem kupferkaschierten Laminat ausgeh\u00e4rtet, um einen Resistschutzfilm zu bilden. Nachdem die kupferkaschierte Leiterplatte ge\u00e4tzt (und manchmal galvanisiert) wurde, um Kupferschaltungen zu bilden, wird der Film mit einer verd\u00fcnnten Alkalil\u00f6sung entfernt, und der Resistfilm verbleibt nicht auf der Leiterplatte, sondern legt die Kupferschaltungen frei. Daher muss die Resistfarbe eine gute Haftung auf der metallischen Kupferfolie aufweisen, korrosions- und galvanikbest\u00e4ndig sein und sich mit einer verd\u00fcnnten Alkalil\u00f6sung vollst\u00e4ndig entfernen lassen.<\/p>\n<p>F\u00fcr UV-Resist-Tinten werden in der Regel anhydridmodifizierte Epoxidacrylharze, hochs\u00e4urehaltige Polyesteracrylharze oder modifizierte Maleins\u00e4ureanhydridharze als Hauptharz zusammen mit funktionellen Acrylatmonomeren verwendet; als Fotoinitiatoren werden in der Regel 651 oder Sulfinon-Fotoinitiatoren wie 2-Ethylsulfonchinon verwendet; die Pigmente sind meist Phthalocyaninblau, die Menge betr\u00e4gt in der Regel etwa 1%, und es muss eine gro\u00dfe Menge an F\u00fcllstoffen wie Talkumpulver hinzugef\u00fcgt werden. Um die Thixotropie der Tinte zu verbessern, muss eine bestimmte Menge an pyrogener Kiesels\u00e4ure hinzugef\u00fcgt werden. Insbesondere ist zu beachten, dass das alkalil\u00f6sliche lichtempfindliche Harz, das eine bestimmte Menge an Carboxylgruppen enth\u00e4lt, nach dem Aush\u00e4rten und der Filmbildung durch Vernetzung korrosions- und elektroplattierungsbest\u00e4ndig sein muss und auch in einer 3%-Natriumhydroxidl\u00f6sung zur Entfernung l\u00f6slich sein muss.<\/p>\n<p>UV-h\u00e4rtbare Druckfarben und Fotoinitiatoren haben eine<b> stark abh\u00e4ngig und synergetisch<\/b> Beziehung. Fotoinitiatoren sind der Hauptbestandteil von UV-h\u00e4rtenden Tinten f\u00fcr die schnelle Aush\u00e4rtung, und die Leistung der Tinte (wie Aush\u00e4rtungsgeschwindigkeit, Haftung, chemische Best\u00e4ndigkeit usw.) wird direkt von der Art, Konzentration und Kompatibilit\u00e4t des Fotoinitiators beeinflusst. Nachfolgend wird ein spezifischer Zusammenhang und Wirkmechanismus zwischen den beiden Faktoren dargestellt:<\/p>\n<h3><strong>1. Fotoinitiatoren sind der \"Ausl\u00f6ser\" f\u00fcr die Aush\u00e4rtung von UV-Farben<\/strong><\/h3>\n<p><!-- lc-qa-start --><\/p>\n<p><strong>Quick answer:<\/strong> In most UV systems, photoinitiators are selected by balancing wavelength fit, through-cure, color control, and line speed. Buyers usually compare a blended package instead of one isolated product.<\/p>\n<p><!-- lc-qa-end --><\/p>\n<ul>\n<li><b>Kernfunktion<\/b>:<\/li>\n<li>Nach der Absorption von ultravioletter (UV) Energie erzeugt der Fotoinitiator aktive freie Radikale oder Kationen, die die Polymerisationsreaktion des Harzes (z. B. Acrylat, Epoxidharz) und des Monomers in der Tinte ausl\u00f6sen, wodurch die fl\u00fcssige Tinte sofort vernetzt und zu einem festen Film aush\u00e4rtet.<\/li>\n<li><b>Ohne Photoinitiator<\/b>UV-Tinte kann nicht durch Licht geh\u00e4rtet werden, und die Korrosionsschutzfunktion kann nicht erreicht werden.<\/li>\n<li><b>Schl\u00fcsselrolle<\/b>:\n<ul>\n<li><b>Absorption von Lichtenergie<\/b>: Der Initiator muss dem Emissionsspektrum der UV-Lichtquelle (z. B. Quecksilberlampe, LED) entsprechen (z. B. muss eine LED mit 395 nm zu einem Initiator mit einer Absorptionswellenl\u00e4nge von 395-405 nm passen).<\/li>\n<li><b>Energie\u00fcbertragung<\/b>: Die absorbierte Lichtenergie wird in chemische Energie umgewandelt, um die Vernetzung des Harzes auszul\u00f6sen.<\/li>\n<li><b>\u00dcberwindung der Sauerstoffhemmung<\/b>: Einige Initiatoren (z. B. wasserstoffabspaltendes Benzophenon + Amin) k\u00f6nnen die hemmende Wirkung von Sauerstoff auf die H\u00e4rtungsreaktion verringern.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h3><strong>2. Die Art des Fotoinitiators bestimmt die Aush\u00e4rtungseigenschaften der Tinte<\/strong><\/h3>\n<h4><strong>(1) Abstimmung des Initiatortyps auf das Tintenharz<\/strong><\/h4>\n<ul>\n<li><b>Radikale Initiatoren<\/b> (z. B. TPO, Irgacure 907):\n<ul>\n<li>Geeignet f\u00fcr<b> Acrylatharz<\/b> Systeme, schnelle Aush\u00e4rtungsgeschwindigkeit, kann aber durch Sauerstoff beeintr\u00e4chtigt werden.<\/li>\n<li>Wird h\u00e4ufig in L\u00f6tmaskentinten f\u00fcr Leiterplatten und in Szenarien mit hohen Anforderungen an die Oberfl\u00e4chenh\u00e4rtung verwendet.<\/li>\n<\/ul>\n<\/li>\n<li><b>Kationische Initiatoren<\/b> (z. B. Thiuramsalze):\n<ul>\n<li>sind geeignet f\u00fcr<b> Epoxidharz<\/b> Systeme. Die Aush\u00e4rtung wird durch Sauerstoff weniger beeintr\u00e4chtigt und ist f\u00fcr die Tiefenh\u00e4rtung geeignet.<\/li>\n<li>Sie werden meist in Druckfarben verwendet, die eine hohe Temperaturbest\u00e4ndigkeit oder eine bessere chemische Best\u00e4ndigkeit aufweisen m\u00fcssen (z. B. einige Verpackungsmaterialien).<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h4><strong>(2) Initiatoren beeintr\u00e4chtigen die Leistung von Druckfarben<\/strong><\/h4>\n<ul>\n<li><b>Aush\u00e4rtungstiefe<\/b>: Tiefenh\u00e4rtende Initiatoren wie Bis-Acyl-Phosphinoxid (BAPO) k\u00f6nnen die vollst\u00e4ndige interne Aush\u00e4rtung von dicken Schichten oder hochreflektierenden (z. B. wei\u00dfen) Druckfarben gew\u00e4hrleisten.<\/li>\n<li><b>Tendenz zur Vergilbung<\/b>: Einige Initiatoren (z. B. ITX) k\u00f6nnen sich nach Lichteinwirkung zersetzen und Chromophore bilden, wodurch sich die Farbe der Tinte ver\u00e4ndert. Es sollten vergilbungsarme Typen (wie z. B. Irgacure 819) gew\u00e4hlt werden.<\/li>\n<li><b>Migration:<\/b> Druckfarben f\u00fcr Lebensmittelverpackungen oder medizinische Anwendungen erfordern die Verwendung von migrationsarmen Initiatoren (wie TPO-L), um zu verhindern, dass Restinitiatoren auswaschen und kontaminieren.<\/li>\n<\/ul>\n<h3><strong>3. Synergistische Optimierung bei der Rezepturentwicklung<\/strong><\/h3>\n<ul>\n<li><b>Konzentration des Initiators:<\/b>\n<ul>\n<li>Ist die Konzentration zu niedrig, ist die Aush\u00e4rtung unvollst\u00e4ndig und die Best\u00e4ndigkeit schlecht;<\/li>\n<li>Wenn die Konzentration zu hoch ist, verbleibt viel Restinitiator, der die Haftung verringern oder Migrationsprobleme verursachen kann.<\/li>\n<li><b>Optimierungsverfahren<\/b>: Die \u00fcbliche Zugabemenge betr\u00e4gt 1-5% der Gesamtmasse der Tinte, wobei das optimale Verh\u00e4ltnis durch Versuche ermittelt werden muss.<\/li>\n<\/ul>\n<\/li>\n<li><b>Gemischte Initiatorenstrategie<\/b>:\n<ul>\n<li><b>Oberfl\u00e4chen- und Tiefenh\u00e4rtung<\/b>: Bei L\u00f6tmaskenfarben f\u00fcr Leiterplatten werden beispielsweise TPO (schnelle Oberfl\u00e4chenh\u00e4rtung) und Irgacure 819 (tiefe Penetration) kombiniert, um eine vollst\u00e4ndige Aush\u00e4rtung zu gew\u00e4hrleisten.<\/li>\n<li><b>Breites Spektrum an Reaktionen<\/b>: Kombination von Initiatoren mit unterschiedlichen Absorptionswellenl\u00e4ngen (z. B. Irgacure 2959 + ITX) zur Anpassung an Lichtquellen mit mehreren Wellenl\u00e4ngen (z. B. Quecksilberlampen).<\/li>\n<\/ul>\n<\/li>\n<li><b>Additive Synergie<\/b>:\n<ul>\n<li><b>Amin-Synergisten<\/b> (z. B. EDAB): Verbessern die H\u00e4rtungseffizienz von Radikalinitiatoren an der Luft.<\/li>\n<li><b>Stabilisatoren<\/b>: Verhindern Sie eine vorzeitige Zersetzung des Initiators w\u00e4hrend der Lagerung der Tinte.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h3>4.
