Description
Technical field
The present invention relates to a kind of manufacture fields, and in particular to network transformer pin tin plating method.
Background technology
Network transformer is mainly used in：Good digital interchanger, SDH/ATM transmission devices, ISDN, ADSL, VDSL,
POE power receiving equipment Integrated Digital Services equipment, FILT optical fiber loops equipment and Ethernet switch etc..
Network transformer is the equipment all having on consumer level PCI network interface cards, be also designated as data pump or can be described as network every
From transformer.There are two its role on one piece of network interface card is main.First, transmission data, the difference that it sends out PHY
The coil coupling filtering of signal differential mode coupling is coupled to by the conversion of electromagnetic field the company of varying level to enhance signal
Connect the other end of cable；When the varying level of the heterogeneous networks equipment room of isolation cable connection, to prevent different voltages from leading to
Cross network cable transmission damage equipment.
In addition to this, network transformer can also play the role of equipment certain lightning protection.
The signal level generated when the chip operation of any CMOS processing procedures (depends on the system of chip always greater than 0V's
Journey and design requirement), PHY output signals are sent to the loss that 100 meters of even longer places have very big DC component.And
If external cable is directly connected with chip, electromagnetic induction (thundering) and electrostatic, it is easy to cause the damage of chip.Again
It is equipment ground method difference, power grid environment difference can lead to that the 0V level of both sides is inconsistent, and such signal passes to B from A, due to
The 0V level of 0V level and the B point of A equipment is different, may result in very big electric current in this way and flows to electricity from the high equipment of potential
The low equipment of gesture.
And the coil coupling that network transformer couples the differential signal differential mode that PHY is sent out is filtered to enhance signal,
And the other end of connected with network cable is coupled to by the conversion of electromagnetic field.Not only make there is no physics between cable and PHY in this way
On connection and change and deliver signal, separated the DC component in signal, can also have been transmitted in the equipment of different 0V level
Data.
There are four row's pins on network transformer, in pairs on the corner of network transformer main body.In order to just
In using network transformer, need to carry out tin plating technique to the pin of network transformer.In existing zincincation, by worker apprentice
Hand holding network transformer progress is tin plating, in this technique, does not simply fail to high-volume and carries out the tin plating of network transformer, and artificial
The position of control network transformer manually, easily leads to that pin on network transformer is tin plating uneven, influences making for network transformer
Use the service life.Also, it since pin is located on the corner of network transformer main body in pairs, when tin plating, needs first to being located at
Two rows of pins progress of network transformer body side is tin plating, network transformer main body is then rotated, to being located at its opposite side
Two rows of pins progress are tin plating, increase worker and pull intensity.
