Tinned vs Bare Copper Terminals: Which to Spec

The part on your spec sheet is the part with the finish, and the finish is the line the price, the life, and the process are read on. The bare copper terminal ships in the copper color, and the tinned terminal carries the silver, and the two are the two the quote is read against, because the tin is the tin that costs the line and the tin that buys the life. The honest answer is that the two are not two versions of the same part. They are two parts for two lines, and the spec that names the one is the spec the year is run on. This article is the three lines the decision runs on, the corrosion line, the solder line, and the cost line, and the split that most of the programs end up specifying. We run both finishes from the same molds in Yueqing, and we will read the three lines with you before the spec is closed.

The corrosion line: where the copper color fails

Bare copper darkens in the air, and the darkening is the oxidation that runs on the surface from the day the part leaves the line. In a dry indoor panel the darkening stays on the shelf, because the connection is made and closed once and the crimp is the crimp that was checked at the line, so the bare part holds for the panel that is made and closed. In the air that carries the salt, the chemical, or the heat of the workshop, the darkening is read on the contact, and the bare part is the part whose contact resistance climbs with the year. Tin holds the copper under the silver, and the tinned part is the part read on the year, the part for the outdoor line, the marine side, and the panel that will not be opened for the life of the machine. The line the buyer reads is the line of the environment, and the dry indoor panel is the environment the bare part runs on, and the air that carries the salt and the chemical is the environment the tin is read on.

The solder line: the process the part is made by

The process the connection is made by is the process the finish is read on, because the tin is the tin the solder wets. The crimped connection holds the bare copper as it holds the tinned copper, so the crimped line runs on either finish, and the bare part is the price on that line. The soldered connection is the joint that wets the tin in the one pass, while the solder on bare copper needs the clean, the flux, and the heat the line takes, so the soldered line is the line the tin is read on. The tinned part is the part for the harness that is soldered, the board that is soldered, and the joint the process runs on, and the bare part is the part for the line that is crimped and the crimp the connection is read on. The line the buyer reads is the line of the process, and the crimp is the process the bare part runs on, and the solder is the process the tin is read on.

The cost line: the price the tin adds and buys

The tin is the tin the line runs, and the run of the tin is read on the price as a premium on the bare part. The premium is small on the order and small on the year, because the bare part that is the contact that climbs is the contact that comes back as the rework, the repair, and the panel that is opened and closed and cleaned. The cost line is the line the two are read against, the bought price on the order and the life cost on the year, and the tinned part wins on the life when the environment is the environment that darkens the copper. The read the buyer makes is the read of the environment and the process together, the dry indoor with the crimp is the line the bare part wins on, and the salt and the chemical with the solder is the line the tin wins on. We quote both finishes on the same part, and the quote that carries the two is the quote the line is read on before the spec is closed.

How we run it

The bare line is the line for the dry indoor panel and the crimped connection, and the tinned line is the line for the environment that carries the salt and the chemical and the process that is the solder. The part for your program is the part read on the two, the environment the machine runs in and the process the connection is made by, and the finish is the finish the two are read on. Send us the part and the environment and the process, and we will come back with the finish the line is read on, the bare for the dry panel or the tinned for the life, and the quote that carries the two. The finish that is the finish for the line is the finish the year is run on, and not the finish read on the day the part is bought.

 

The line	How the bare part reads it	How the tinned part reads it
The environment	The dry indoor panel made and closed once	The air with the salt, the chemical, the heat
The process	The crimp that holds either finish	The solder that wets the tin in the one pass
The price	The price without the premium	The price that carries the tin run
The year	The contact that climbs in the wet air	The surface that holds for the life of the machine

 

1. Name the environment the machine runs in, the dry indoor or the air with the salt.
2. Name the process the connection is made by, the crimp or the solder.
3. Read the corrosion line, the copper that darkens in the air the panel runs in.
4. Read the solder line, the finish the solder wets in the one pass.
5. Read the cost line, the premium on the order against the life on the year.
6. Send the part and the two lines to the maker, the finish the quote carries.

We are Yueqing Gaopeng Electric, a terminal manufacturer in Yueqing since 2016, and the two finishes we run are the two the line is read on, the bare copper for the dry panel and the tinned part for the life. Send us the part and the environment and the process, and we will come back with the finish the line is read on and the quote that carries the two. The part that is the part for the year is the part read on the three lines, the corrosion and the solder and the cost, and not the part read on the color alone.
