Tavola di placcatura Au
Au Plating Board Manufacturer & Assembly – One-stop service
According to the surface treatment, There are following eight kinds of PCB boards: Hot Air Leveling, Gold finger Board, Cardon Oil Board, Au plating board, OSP board, Immersion Au board, Tavola di latta per immersionee Immersion Silver Board.
Now Pls let me introduce Au Plating Board for you:
1. Plating History
Electric gold plating technology was invented by Elkington’s in 1840, which pioneered gold plating technology. Gold plating technology not only effectively utilizes the characteristics of gold but also USES gold to the key parts needed. It is a new gold saving process, with high economic benefits and extensive practical value.
Electric plating was divided into thick gold plating, flash gold plating and gold plating color PCB board is selective partial gold-plated, generally USES the low cyanide acidic plating technology, using potassium aurous cyanide electroplating gold ions, a price because the price of gold excellent electroplating efficiency, low to contain a certain amount of free cyanide in cyanide gold plated venom in acid a in the price of gold plating, easy to form trivalent gold by anodic oxidation, so you need to add gentle reductant, reduce or even to hinder the third-order gold ions form the plating solution in plating solution can add sulfuric acid phosphate citric acid amino acid and amine, etc.
2. Compare with Immersion Au board, gold plating range is only a small part
The main characteristics of Au Plating Board are as follows:
- The wettability of the electro gold board is equal to that of op. The wettability of anodized board and tin-impregnated board is the highest among all PCB’s.
- The thickness of electro gold is far greater than that of gold, but the flatness is not as good as that of gold.
- Electrogold is mainly used for gold finger (wear resistance), and many welding pads are made.
3. Au Plating Board’s characteristics:
- High electrical conductivity.
- Good welding performance.
- Good ductility.
- Corrosion resistance.
- Wear resistance.
- Color resistance.
- Good reflection performance infrared.
- Alloy wear resistance.
- Rating thickness 1mm, the thinnest 1 micro inch.
What kind of PCB board needs gold plating?
Le schede PCB con il dito d'oro devono essere rifinite con placcatura in oro., Ma l'altra area della scheda al di fuori del dito d'oro, possiamo scegliere un altro trattamento di finitura in base alla situazione della latta o del processo spray, come l'oro pesante, e cioè solitamente oro pesante + processo di placcatura e stagno spray + dita placcate in oro, occasionalmente alcuni designer per risparmiare tempo o costi scelgono un intero modo zedoary per raggiungere un obiettivo, ma oro pesante a corto di spessore di placcatura, se il dito d'oro spesso elimina la connessione il problema sarebbe placcato in oro perché la superficie della piastra di saldatura con uno strato d'oro, quindi una buona saldabilità, la scheda ha prestazioni stabili.Perché la superficie del pad ha uno strato d'oro, quindi la saldatura è buona, le prestazioni della piastra lo sono stabile.
