Philips announces new flagship LED light cup

At the recent Frankfurt exhibition in Germany, Philips launched its new flagship LED lamp cup, which is expected to be an ideal replacement for general illumination sources such as incandescent lamps, halogen lamps and compact fluorescent lamps.

Philips' new flagship LED lamp cup uses the latest LUXEON Rebel LED chip, which is claimed to be the smallest surface mount power indicator available today, providing excellent color light output while providing excellent color correction. The chip can last 45,000 hours of illumination and has a lifetime that is 50 times that of an ordinary incandescent lamp. Compared to standard cold light low-power halogen lamps and incandescent spotlights, the chip can save up to 80%.

If you install this product in a hotel lobby, stairs, parking lot and other places that require 24-hour lighting, you can save the buyer a lot of maintenance costs.

In addition, because the flagship LED lamp cup does not contain any harmful substances such as lead or mercury, it can effectively help the owners to improve the safety of the business environment.

Gold Fingers PCB is gold-plated terminal of a card-edge connector, usually, Fingers are fabriacate by flash gold (hard gold) and the gold thickness is requested to be from 3u"to 50u" because fingers are mainly used for pluging for many times.

When PCBs will be repeatedly installed and removed electroplated gold is used for edge-connector contacts or as they are more commonly known: Gold fingers.
Gold fingers are edge connector contacts and are used to electroplate pads onto the board. The idea behind a gold finger is to help protect the Printed Circuit Board prototypes from wear and tear. If applied correctly, with the right thickness, they are expected to last upwards of 1,000 cycles before there is any need of repair.

These little fingers are quite versatile, and they have many different uses depending on their intended purpose. Some of these uses include:

 
Provides connections for network transfer data.
 Attaches specialty adaptors.
 Connects different devices to the board.
 Can be used as audio adaptors.

 
Here is several design rules are required for gold fingers PCB / PCB edge connectors.

1. No plated through holes are allowed in the plated area
2. No solder mask or silkscreening can be present in the plated area
3. For panelization, always place gold fingers facing outward from the panel center
4. Connect all gold fingers with a 0.008" conductor trace at the edge to allow for manufacturing

5. Features can be placed on one or both sides to a depth of 25mm from the outside edge
