Abstract

The ironing solution is designed primarily for the galvanic ironing of copper soldering tips and crucibles for melted solder as a protection against the melt-down of copper in the solder and against the influence of melting agents. The current methods of protection of the soldering tips are putting on a thin layer of metal, most often by ironing, are either economically demanding or insufficient. Imperfections of the current situation are avoided by an ironing solution for galvanic ironing of objects made of copper and its alloys where one litre of water solution contains 120 to 800 g of iron dichloride, between 3 and 50 g of manganese dichloride, 5 to 100 g boric acid, from 50 to 150 g of concentrated hydrochloric acid and 0.2 to 10 g of a soaking agent.

Description

Vynález rieši železiaci roztok pre galvanické poželezovanie predmetov z médi alebo jej zliatin s prevažujúcim obsahom médi v zliatine.The invention provides a ferrous solution for the galvanic ironing of objects from a medium or its alloys with a predominant medium content in the alloy.

Pri výrobě výrobkov elektroniky, ale aj v iných priemyselných odvetviach, je ešte stéle v značnej miere využívaná technologie spájkovania súčiastok elektrickými hrotovými spá j ко vačkami. Měděné hroty spájkovačiek sú však pri spájkovaní nadmeme opotřebovávané v dósledku rozpúšíania médi v spájke. Popřední výrobcovia riešia tento problém poželezovaním spájkovacích hrotov, čo predlžuje životnost hrotu spájkovačky až stonásobné. Najzaužívanější spósob poželezovanie je žiarové nanášanie. Tento spósob poželezovania vyžaduje náročné technologické zariadenia, ktoré zvyšujú náklady na poželezenie. Značná investičná náročnost technologie žiarového nanášania zabraňuje využit poželezovanie měděných hrotov spájkovačiek u výrobcov s nižšou výrobou, resp. spotřebou spájkovacích hrotov. To vedie к zbytočenému plytvaniu meňou, ktorá je na výrobu spájkovacích hrotov používaná. Iným, velmi obmedzene používaným spósobom poželezovania měděných hrotov spájkovačiek, je galvanické poželezovanie. Obmedzené používanie galvanického poželezovania měděných spájkovacích hrotov je zapříčiněné tým, že železiace kúpele nevytvárajú dostatočne odolný povlak, ktorý praská, odlupuje sa od základného materiálu, resp. je nedostatočne odolný posobeniu tavidiel a spájky.In the manufacture of electronics products, as well as in other industries, the technology of soldering components with electric spike joints is still widely used. However, copper soldering tips are worn excessively during soldering due to the dissolution of the media in the solder. Leading manufacturers solve this problem by ironing the soldering tips, which increases the lifetime of the soldering tip up to 100 times. The most commonly used method of ironing is by hot dipping. This method of ironing requires demanding technological equipment, which increases the cost of ironing. Significant investment demands of the heat deposition technology prevent the use of ironing of the soldering iron tips at the producers with lower production, respectively. consumption of soldering tips. This leads to unnecessary waste of the currency used to manufacture the soldering tips. Another, very limited method of ironing copper soldering iron tips is galvanic ironing. The limited use of the galvanic ironing of the copper soldering tips is due to the fact that the ironing baths do not form a sufficiently resistant coating that ruptures, peeling off from the base material or from the base material. is insufficiently resistant to soldering fluxes and solder.

Vyššie uvedené nedostatky odstraňuje železiaci roztok pre galvanické poželezovanie predmetov z médi alebo jej zliatin s prevažujúcim obsahom médi v zliatine, podlá tohoto vynálezu, ktorého podstata spočívá v tom, že železiaci roztok obsahuje chlorid železnatý v chlorid manganatý v boritú v množstve solnú koncentrovaná v množstve 0,2 až 10 množstve množstve kyselinu kyselinu zmáčadlo nou vodou.The above-mentioned drawbacks are eliminated by an iron solution for galvanic ironing of objects from the medium or its alloys with a predominant medium content in the alloy according to the present invention, which is characterized in that the iron solution contains ferric chloride in manganese chloride in borate in an amount of 0 , 2 to 10 amounts of acid acid acid wetting water.

Ďalej bude popísaný jeden příklad železiaceho kúpeía podía tohoto vynálezu. Železiaci roztok pre galvanické poželezovanie predmetov z médi alebo jej zliatin s prevažujúcim obsahom médi v zliatine, s výhodou pre poželezovanie spájkovacích hrotov a téglikov na roztavená spájku, obsahuje na jeden liter vodného roztoku chlorid železnatý v množstve 600 g, chlorid manganatý v množstve 10 g, kyselinu boritú v množstve 30 g, ml koncentrovanéj kyseliny solnej a ml zmáčadla, s výhodou roztoku laurylsíranu sodného s kyselinou L-askorbovou, vzniknutého rozpuštěním 30 g laurylsíranu sodného a 6 g kyseliny L-askorbovej v 64 g destilovanej vody.One example of a rail bath according to the present invention will be described below. The iron solution for the galvanic ironing of articles from the medium or its alloys having a predominant medium content in the alloy, preferably for ironing soldering tips and crucibles to molten solder, contains per g of aqueous solution 600 g iron manganese, 10 g manganese chloride, boric acid in an amount of 30 g, ml of concentrated hydrochloric acid and ml of a wetting agent, preferably a solution of sodium lauryl sulfate with L-ascorbic acid, formed by dissolving 30 g of sodium lauryl sulfate and 6 g of L-ascorbic acid in 64 g of distilled water.

Najvýhodnejšie použitie železiaceho roztoku podlá vynálezu je pre galvanické poželezovanie měděných spájkovacích hrotov a téglikov na roztavená pájku, ako ochrana proti rozpášřaniu médi v spájke a před účinkami tavidiel.The most preferred use of the iron solution according to the invention is for the galvanic ironing of copper solder tips and crucibles to molten solder, as protection against the spreading of the medium in the solder and from the effects of fluxes.
