SEEKING REEL-TO-REEL TINNING LINE AND RELATED ITEMS

 

WE ARE A COMPANY WHICH WISHES TO INSTALL A REEL TO REEL ELECTRO TINNING OR HOT DIP TINNING PLANT FOR COATING PURE TIN ON COPPER AND BRASS STRIPS OF A WIDTH OF 380 MM MAXIMUM. WITH A STRIP THICKNESS RANGE OF .8 MM TO .15 MM.

WE ARE CONFUSED WHETHER WE SHOULD GO FOR AN ELECTRO-TINNING LINE OR A HOT DIP LINE.

WE WOULD APPRECIATE IF YOU COULD GIVE US THE FOLLOWING INFORMATION:

1. NAMES AND ADDRESSES OF THE COMPANIES MAKING HOT DIP AS WELL AS ELECTRO TINNING REEL TO REEL LINES FOR COPPER AND BRASS.

2. WHICH IS A BETTER TECHNOLOGY HOT DIP OR ELECTRO-TINNING.

3. SINCE OUR PRODUCT WILL HAVE TO FURTHER GO FOR MAKING CONNECTORS WHAT SHOULD BE THE THICKNESS OF COATING.

4. WHICH INSTRUMENT IS THERE FOR CHECKING THE THICKNESS OF COATING ON THE SURFACE OF COPPER AND BRASS.

5. WHICH IS A ECONOMICAL PLANT A HOT DIP ONE OR A ELECTRO TINNING ONE.

PLEASE PROVIDE US THE NAME AND ADDRESS OF THE COMPANIES MAKING CHEMICALS FOR HOT DIP AS WELL AS ELECTRO TINNING REEL TO REEL LINES FOR COPPER AND BRASS

YOUR EARLY REPLY SHALL BE HIGHLY APPRECIATED.

BEST REGARDS,

Hi, Vidu.

1. Sorry, but we can't ask our advertisers, who make this forum possible, to bear the costs of maintaining contact info for their competitors who don't advertise here :-)

2. Both technologies are widely practiced, which would not be the case if one were better. Generally, electroplated coatings would be thinner than hot dipped coatings.

3. The tin thickness is a function of the application and may involve electrical engineering issues as well as plating or hot dipping issues. But, again, when you know the thickness you will be able to get a good handle on whether to electroplate or hot dip.

4. X-ray fluorescence thickness testers and beta backscatter thickness testers probably would both work for this application.

5. I don't think there is an awful lot of difference in capital cost between plating and hot dipping.
