Kt Kingtronics Contrast between GPP (Glass Passivated) and OJ (Pickling) of TVS Devices

23 Mar 2015

1. Construction:
(Figure 1) OJ structure
(FIG. 2) GPP structure

2. Process:
Protection of the biggest differences between the two products in the PN junction.
OJ structure of the product, the use of glue to protect knot, then at 200 degrees temperature curing. P-N junction obtain protection voltage.
GPP structure of the product, the chip PN junction is under the protection of the passivation glass, sintered glass frit is 800 degrees around the melting, the glass layer is formed after cooling. This glass layer and melt into one chip, can not be separated by mechanical means.
And OJ protection glue, just covering the PN junction surface.

3. Feature Comparison:
1) due to the different structure, when external stress (for example, were angled handle), thermal shock devices, under the plastic package if there is leakage, so the situation. OJ products, the protection of plastic and silicon is not firmly bound to protect a bad situation occurs, the device appears certain failure rate. GPP product similar situation does not occur.
2) High GPP diode reliability. First, GPP at room temperature, leakage than OJ's going small. It is particularly important HTRB (high temperature reverse bias, is a measure of reliability of the most important symbol of parameters) GPP much better, OJ products can only withstand HTRB 100 degrees around. The GPP when the temperature reaches 150 degrees, still performed very well.

4. Description:
OJ previously packaged products is limited to the axial DO series, so many customers are using on-chip package (SMD) products. Because chip product, then only use GPP chip package.
But now, there have been a chip package OJ products. So be sure to pay attention to distinguish the selection.

Kt Kingtronics Quartz Crystal Precautions for Use

20 Mar 2015

•Good shock measures to ensure the Quartz Crystal don’t fall to the ground during use.

• When storing crystals, anti-extrusion measures should be prepared and stored in a dry and ventilated place, avoid damp Quartz Crystal.

• When the solder, solder temperature is not too high, the role of the solder time not too long, so as not to produce an unstable change occurs within the Quartz Crystal.

• Ensure two-pin solder points are not connected, or will lead to Oscillator is stopped.

• The shear pin, should pay attention to the effects of mechanical stress.

• Solder, it should be cleaned to prevent the insulation resistance don’t meet the requirements.

Kt Kingtronics Applications of Quartz Crystal and Oscillators

9 Mar 2015

Quartz Crystal also known as Quartz Crystal Oscillator. That was accomplished by means of "Piezoelectric" effect.
That is "Supply Voltage", Kingtronics common voltages are 1.8V, 3.3V, 5.0V.
The semiconductor devices and resistance capacitance element worked together, could constitute a Quartz Crystal Oscillator.

Quartz Crystal Applications:
1, QKT-HC49U (HC-49U) suitable for electronic products with broad spaces such as communications equipment, televisions, telephones, electronic toys;
2, QKT-HC49U/S (HC-49U/S) is suitable for all kinds of space height restrictions thin and small electronic equipment and products;
3, QKT-HC49 SMD (HC-49U/S SMD) prevail surface mount products, applicable to all types of ultra-thin, small computers and electronic devices;
4, 3*8 Tuning fork Cylindrical quartz crystal resonators suitable for space-constrained timing frequency stabilization of electronic products such as timers, electronic clock, calculator, etc.

Kingtronics offers passive leaded quartz crystal HC49U, HC49S, SMD quartz crystal HC49SMD
and 3225 SMD Crystals. We also produce active 3225, 5032, 5070 SMD Oscillators.
We produce millions pieces of Quartz Crystal and SMD Oscillators monthly, the volume is keep increasing. Free samples for testing.

Kt Kingtronics Happy Lantern Festival!

6 Mar 2015

Kingtronics wish everybody Happy Lantern Festival with your families and friends O(∩_∩)O~

In the afternoon, our Kingtronics everybody eat tuanyuan.

It is small dumpling balls made of glutinous rice flour with rose petals, sesame, bean paste, jujube paste, walnut meat, dried fruit, sugar and edible oil as filling.
You can drop these balls into boiling water and cook them for about 8 minutes until they float. Then you can eat them.
Tangyuan in Chinese has a similar pronunciation with "tuanyuan”.
The reason that soup dumpling is popular, because they have a meaning of reunion. Traditionally, people eat Tangyuan on the night of the Lantern Festival, because it symbolize family unity and happiness.

At night , people will try to solve the puzzles on the lanterns.

Here share photo, haha, good enjoy them!
