Is it important to select air conditioning during peak season?

The same is true for home appliances. Many household electrical appliances have to pay more attention to the selection than the selection, and installation and after-sale use are also important. Air conditioners have always had the industry's claim of "three-point quality seven-point installation," and many friends who bought air conditioners for the first time did not pay attention to them.

Purchase and purchase

During the holidays, we have seen a wide variety of promotional sales machines on the market. It is important to see how we can make purchases based on our own needs.

Price point

If you think of the benefits and low prices, then after you decide to purchase, you must implement promotions with promoters. You can do more than you want. Stores and businesses will have a lot of gifts during the holidays. Don't be afraid. Don't be afraid. , bold and salesperson ask for.

Spotlight energy savings (changes and changes)

At present, the air conditioners on the store are all energy-saving products. Therefore, it is important to pay attention to buying the inverter or fixed-frequency air conditioner. Of course, it depends on individual needs and the budget to determine the purchase direction.

Is the function really important?

The function of the air conditioner on the store is various, and many consumers feel that they do not know what to choose. In fact, they can be allocated on demand and they can purchase it for their own use.

Installed on acceptance

First, look at the specific model of the product. When out of the box, be sure to carefully check whether the model on the purchase ticket matches the model of the door-to-door delivery product. When it is completely correct, it can be opened.

Second, look at the appearance. Look at the appearance of the product and other details such as whether there are scratches and other conditions. If it is a refrigerator washing machine, it depends on whether the surface has been bumped, bumps, etc., etc., so that the staff can only leave after confirming.

The final course is the operation of home appliances at the time of initial use. Air conditioning products, then we must understand, to see whether the air conditioning and refrigeration noise is too large, there is beyond the normal range, if there is abnormal noise, the first time to contact the manufacturer for after-sales regulation, and air conditioning will have to be installed Debugging allows staff to leave. Don't turn on the unit the next time it is used, and the air conditioner will not function properly.

Do you know what is ENEPIG in PCB?
 What is ENEPIG?ENEPIG-Electroless Nickel Electroless Palladium Immersion Gold is a surface finish for Printed Circuit Boards.ENEPIG works well with lead free and conventional eutectic solder alloys.This is the best way for gold wire bonding. Advantages for ENEPIG:

1.[Black Nickel" free – no possibility of grain boundary corrosion of nickel surface by immersion gold
2.Palladium acts as an additional barrier layer to further reduce copper diffusion to surface, thus ensuring good solderability
3.Palladium completely dissolves into solder, without leaving an excessively high P% rich interface, exposing an oxide-free nickel surface allowing reliable formation of Ni/Sn intermetallic
5.Withstands multiple lead-free reflow soldering cycles
6.Demonstrates excellent gold wire bondability

7.Process costs substantially lower than electrolytic nickel gold or electroless nickel electroless gold
