• Selection of tableware can not be careless, pay attention to these details!

    With the accelerated pace of society, people's material and cultural needs are also increasing, especially in the selection of items is no longer the previous can be practical, but bamboo knife can meet the aesthetic needs, such as tableware. However, some of the more beautiful tableware is not suitable for our use, we must pay attention to the details of the choice of tableware, do not pay attention is equivalent to eating poison, I'll show you.

    Painting is toxic because of the addition of co-solvent

    Ceramic tableware design with very easy to rust, not corrosive, non-absorbent, acid and alkali resistant, high temperature resistant characteristics, more suitable for businesses to steam, boil, burn, bake, etc.. And now the ceramic tableware added a color, pattern more fashionable, the style is more varied, by the influence of consumers themselves love. However, an important national development quality for testing and analysis of the results of the study shows that 1/4 of the ceramic tableware lead and cadmium and other heavy metal technology content exists in serious excess of the standard, is substandard products.

    One of the important loess of painted ceramics to produce toxicity is to ensure a good combination of pigment and porcelain body, in the painted ceramics added some co-solvent, co-solvent contains lead, cadmium and other toxic substances, easy to enter the body through food, so painted ceramic tableware is toxic.

    Health countermeasures:Buy unreliable tableware, you can go home and soak it in vinegar for a few hours. If you find a significant change in color, you do not need it. When we buy glazed products, we should also pay attention to whether the pattern color is bright. If it is not bright, it means that the amount of dissolved lead and cadmium is often very high. So do not buy Sam Wu ceramic products just to be cheap. There is no safety guarantee.

    Imitation porcelain tableware, hot water for soaking raw formaldehyde

    Imitation porcelain tableware (melamine tableware) is not easy to break and favored by many housewives. However, they do not know what this tableware is made of, but when they hear the seller say that it is resin, they believe it. Resin is also divided into melamine resin and urea-formaldehyde resin.

    Imitation porcelain tableware is the use of melamine formaldehyde resin with wood pulp filler made of molded products. Melamine reacts with formaldehyde to produce a polymer called melamine resin. It is stable in boiling water and can even be used at 150 °C. Urea formaldehyde resin is the reaction of urea and formaldehyde, which are separated at a certain temperature. This is the reason why some poor quality imitation porcelain tableware has a pungent smell after cooking in hot water: formaldehyde. So you have to be very careful.

    So, some tableware looks good and cheap, in fact, you must be careful when you buy it, pick it up and then buy it home. I am here to tell you that we must consider carefully when we buy tableware and not to be greedy for a small price and cause poisoning. For the sake of your health, please choose the regular supermarket to buy tableware, I wish you good health.

  • Worth the customer's selection of the microphone using these features !

    one: The microphone should have the outstanding traits of lower make contact with sound.

    Hand-held wireless lapel microphone have an impact around the regular seem quality, mainly because contact noise will cause friction concerning the hand as well as the palm, particularly the wi-fi microphone itself incorporates a sensitive pre-amplifier, which makes the touch sounds far more really serious and gets to be a complex bottleneck. Commonly, wi-fi microphones do not have specialist structure knowledge, as well as in get to reduce manufacturing expenses, thick circuits are applied, low-priced audio heads, shock-absorbing suspension layout and affordable tube floor procedure are selected, therefore the seem quality is not apparent, along with the evident touch sounds in the microphone can't be triumph over. , Make the initial seem deteriorate, so when picking a high-quality wireless microphone, you must pay back unique consideration to selecting an extremely clear sound high-quality and ultra-low tactile noise traits.

    two: Has the purpose of eradicating interruption or instability of audio

    Due to the attraction and reflection with the encompassing ecosystem, the wi-fi microphone with the transmitting sign antenna features a blind location, which leads to the output sound to generally be interrupted or unstable. As a way to remedy this problem, the ideal final result may be achieved only by adopting a far more highly developed automated variety obtaining system.

    The low-cost dual-band receivers now well known in the marketplace normally don't have this automatic selective reception purpose. The above mentioned shortcomings can not be averted and can only be employed in short-distance home karaoke occasions. In qualified locations or end users who concentrate to sound top quality, they need to decide on an computerized variety obtaining program that fulfills the audio high quality demands so as to acquire fantastic general performance.

    three. It has the operate of protecting against sound and loud noise due to interference all through standby

    Normally, receivers are typically created along with the key function of mute management handle (Squelch Manage). When the power may be turned on with no a microphone signal enter or maybe the signal toughness is appreciably lower than the usual particular signal-to-noise ratio with the organization, the mute control circuit style will routinely convert from the output. Modular circuit, the most crucial receiver can not be completely muted to forestall sound output. In the event the microphone sign is turned on, the receiver instantly starts off to activate the mute circuit, making it possible for the audio circuit to output the microphone audio. But when the microphone electric power is turned on and off, or once the microphone sign is turned off, sometimes we come across issues past the signal interference with the mute management exercise intensity examination above, and also the receiver mute circuit will also be thought to be these cultural shock noises and interference sound activation approaches The output sound is loud.

  • Why will need X-ray inspection in PCBA ?

    X-ray InspectionX-ray is normally referred to Automatic X-ray inspection (AXI), a kind of brief wavelength and strong electromagnetic wave, the wavelength of X-ray is shorter compared to wavelength of obvious mild (about 0.001 ~ 10 nanometers). The photon electrical power tens to hundreds even hundreds of occasions larger sized than visible light-weight photons power. It had been learned by a German physicist - Wilhelm Konrad Rontgen in 1895, so it is also called “Rontgen Ray”. X-ray is highly penetrating, it could possibly penetrate lots of substances which might be opaque to seen mild. X-ray has the influence of penetration, ionization, fluorescence, heat, refraction and the like, the PCBA manufacturing subject primarily uses its penetration effect, is one of an important actions for quality-oriented PCB makers.

    The 's high repeatability accuracy serves to boost production. The unique angle for sample inspection also makes it suitable for mass testing.

    In recent years, the region array factors like BGA, QFN, CSP, and flip chips, are aplicate wider and broader during the electronics producing. These types of as BGA, comparing with other factors, it's got numbers of pins, smaller sized inductance and capacity amongst pins and superior cooling functionality. On the other hand, the BGA also has shortcomings, for example, soon after the SMT, the solder joints underneath the package deal can rarely be judged the soldering good quality by eyes or AOI screening.

    X-ray gear is based about the strong penetrability of X-ray, the sunshine tube emits X-ray beneath higher pressure, that may efficiently penetrate the objects to be examined, the graphic accomplish is numerous by unique density and thickness, as a result to realize the solder details detection. In an effort to make sure the soldering excellent, an increasing number of suppliers are selecting X-rays to examine the parts which the soldering joints have been concealed.
