Why do items packaged in vacuum bags become moldy? The vacuum bag is a kind of vacuum bag that prevents air from entering. Microorganisms and bacteria cannot survive in the bag. It can greatly increase the shelf life of the food in the bag and greatly extend the storage time of the food.

Generally, vacuum bags can be divided into two types of materials: one is a vacuum bag made of transparent material, and the other is a vacuum bag made of aluminum foil. The price and advantages of each material are different, and they all have their own advantages. The conventional thickness of vacuum bags can be divided into eight wires and eighteen wires. Sometimes thicker is not always better. It depends on the products you are loading. Of course, for sharp objects, thicker is always better. Some products may become moldy in their packaging bags. What causes this?

Mildew of goods in vacuum bags is mostly caused by the following reasons:

1. The packaging material has low thermal insulation - carbon dioxide and methane in the natural environment are transferred into the carton through the packaging bag, causing residual bacteria to inhabit and mate, especially at low temperatures. This is especially true in low-temperature natural environments.

The second is that the packaging material has low mixing fastness - the composite film used in the packaging bag has low peeling strength between single-layer films, that is, the mixing fastness between single-layer films in the composite film is low, making it difficult for mixed cell membranes to peel off. The layer effect results in an increase in the overall performance of the composite membrane, such as positive resistance.

The third is that the raw material carton manufacturing process has little air tightness - the packaging bag body has little air tightness or heat sealability. When the raw material carton is placed for a long time, it is difficult for the raw material carton to leak slowly.

Fourth, the disinfection is incomplete-that is to say, some bacteria remain in the raw material cartons. These bacteria will inhabit and mate in large numbers when encountering an environment with suitable concentration, temperature or concentration.

We have a few suggestions for overcoming problems:

1. Pay attention to the oxygen permeability, water vapor permeability, container efficiency (negative pressure method), heat sealing wind speed, and peel strength of the packaging material.

2. Select materials with low barrier efficiency and poor mixing fastness or increase the volume of original packaging materials.

3. It improves the sterilization performance and increases the sealing volume of  heat sealing.

Common output anomalies

Power supply is an essential core component of electrical equipment. We usually hope that it is stable, reliable, high-precision, and high-performance. We can check these indicators from its technical manual. However, when we test in the laboratory or in actual applications, we often find that the test parameters do not match the nominal parameters. Usually there are the following situations:

1. The output voltage is low or high;

2. The output ripple noise exceeds the specification;

3. There is no output after working continuously for a period of time;

When we encounter these problems, how should we analyze, confirm and eliminate the problems? Next we will analyze the problems one by one

1. The output voltage is low or high

Usually, there are two reasons why the output voltage is low or high:

1) Accidentally touching the adjustable resistor:

Judgment method: Use a multimeter to directly measure the output terminal voltage to determine whether it is the standard output voltage;

Solution: You can rotate the adjustable resistor according to the direction on the label to appropriately increase the output voltage to meet actual needs;

2) The distance between the customer load and the power supply is too long, and the output line loss is too large.

Judgment method: test and compare the voltage at the output terminal of the power supply and the voltage at the input terminal of the customer's load;

Solution: It is recommended to shorten and thicken the wiring between the power supply and the load;

2. The output ripple noise exceeds the specification.

Typically, there are three reasons why output ripple noise is out of specification:

1) The ground loop introduces high-frequency signal interference, and the oscilloscope bandwidth setting is large

Judgment method: Check whether the method of testing ripple noise complies with the recommended method and wiring method in the technical manual;

Solution: Use correct testing methods. Inappropriate testing methods will cause test distortion, lead to misjudgment of results and other problems. Usually during ripple and noise testing we will limit the bandwidth, which mainly depends on the operating frequency range of the module under test. Take the power module as an example. Usually the operating frequency of the power module is below 500KHz, and the frequency of switching noise is also mostly below 5MHz. Therefore, during the test process, it is recommended to limit the bandwidth to 20MHz, so as to ensure that the tested is the ripple noise generated by the real power supply. At the same time, in order to avoid interference on the ground line of the oscilloscope's power supply during testing, it is recommended to cut off the ground pins on the oscilloscope's power line.

        Conventional testing methods are parallel line testing method and dependent testing method. The parallel line testing method is as follows:

Capacitor C1 in the figure is a ceramic capacitor; C2 is an electrolytic capacitor. The default values of C1 and C2 are 1uF and 10 uF respectively;

The test method is as follows:

Compared with the conventional wire-splitting test, the lean-to test method mainly reduces the area of the ground loop to avoid coupling interference in the ground loop during the test, which affects the test results. The main method is to remove the ground clamp as shown in the picture and directly use the copper ring on the probe as the ground. This can effectively avoid the impact of the external electromagnetic environment on the test.

2) The N line of the isolated power module or the input ground is short-circuited to the output negative pole.

Judgment method: Check whether the N line of the power module/input ground-output ground is short-circuited, and check whether there is a negative ground point on the back-end load board;

Solution: It is not recommended that customers connect the isolated power module N line/input ground-output ground together. If the actual application requires the negative pole to be grounded and the requirements for EMC and ripple noise are not high or there are no requirements for isolation voltage, the ground can be shared. use;

3) There are high-power and strong interference equipment or components near the power module

Solution:

a. The customer system layout keeps the power module away from high-power equipment;

b. Add filter peripheral circuit to the front end of the power module;

c. The output leads of the power module should be shortened to reduce noise coupling. If necessary, a metal shell can be used to shield external interference;

By chance, I came across the single-color temperature smart dimming driver that we have been looking for. The main living room lights and ceiling lamps mainly produced by our company are instantly dazzling. They can not only be infinitely dimmed, but also flicker-free throughout the process, and can also be controlled remotely.

In order to understand smart homes, as well as supporting products and services, I have been talking about smart switches in the past few days. Some people say that single-fire smart wall switches cannot be connected to smart dimmer lights, or even some ordinary LED lights. Is this true?

Controllable switch + home circuit = smart switch?

Since the switch controls the light on and off, the smart switch intelligently controls the light on and off. So, does the home circuit + controllable switch become a smart switch? From this, can remote control and electrical equipment linkage be achieved? Let's explore this issue below.

Replace the mechanical switch directly with an intelligent control module

When the module is disconnected, the module itself loses power and the entire circuit is disconnected, making it impossible to remotely turn the switch on again. It's a bit like locking yourself out without a key when you go out, so this method is unreliable. Directly adding a device to the switch that receives instructions and controls it cannot achieve the effect of a smart switch.

It can be seen that controllable switch + neutral line transformation + household circuit = zero fire intelligent switch circuit

In the above circuit, because the controllable switch cuts off its own current after disconnecting the circuit, does the formula of controllable switch + neutral line + household circuit work?

Add a neutral line to the switch so that the switch has an independent circuit, so that the switch can supply power independently, and the line switch of the light will not affect the switch operation. This is the zero-fire switch solution.

The formula of controllable switch + neutral line transformation + household circuit = zero fire smart switch circuit is feasible.

Controllable switch + live wire modification + home circuit = single fire intelligent switch circuit

In addition to the neutral wire, household circuits also have live wires. Since transforming the neutral wire can achieve the effect of smart switching, is it also possible to transform the live wire? That is, controllable switch + live wire modification + household circuit. Is this formula feasible?

By modifying the circuit: instead of using mechanical switches to physically disconnect the circuit, add loads to the switch and lamp circuits. When the switch is closed, due to the load, only a small current passes through the switch and the bulb. The current passing through is too small to light the bulb while maintaining the switch operation. This solves the problem of a single fire switch.

However, it should be noted that the load must ensure that the current passing through it is small enough to not light up the bulb while maintaining the switch operation. Therefore, the single-fire switch has certain requirements for the power of the lamp. If the power of the lamp is too small, it will be easily lit or flicker by the small current passing through (this is also the reason why the single-fire switch load lamp on the market generally has a minimum power of 3W), and It is also necessary to pay attention to the rated power of each circuit of the single-fire switch.

A large part of automotive electronic products now is compatibility design for different car companies. No matter how compatible it is internally, when it comes to external requirements, it is necessary to determine the connection interface requirements, including installation location, structure and electrical content. One prominent problem is Connector selection. Automotive connectors and wiring harnesses are carriers for controlling electrical signals in automobiles. They organically connect vehicle central control components with automobile control units, electrical and electronic execution units, and electrical devices to form a complete automobile electrical and electronic control system.

(1) The content and quantity of automotive connectors and wiring harnesses in in-car electronic technology is also an important indicator of car function and performance.

(2) Automotive connectors, a single vehicle requires approximately 200 wire harnesses and more than 350 connectors

Figure 1 The whole vehicle wiring harness design requires a lot of connections.

When we choose a connector, we first need to consider the particularity of the automotive connector. Automotive connectors are also subject to standards set by different vehicle companies. The basic international standard is ISO 8092-2005, which is divided into four parts:

(1) ISO 8092.1 Dimensions and special requirements for single-wire chip connectors

(2) ISO 8092.2 definition, test methods and general performance requirements

(3) ISO 8092.3 Dimensions and special requirements for multi-wire chip connectors

(4) ISO 8092.4 Cylindrical plug connectors for single-wire and multi-wire plug-in connections Dimensions and special requirements

Since international standards are the result of games, many things are determined by manufacturers as a basic direction. However, the test parameters, test items and test methods are no longer in line with the current development status of connectors, so they are basically divided into three regional standards. Represents some of the requirements of the US, European and Japanese automotive industries.

1) The connector performance specification USCAR-2 formulated by the American Society of Automotive Engineers can represent the development status of connectors in terms of test parameters and test items, and is more operable in terms of test methods. Standards such as GM's GMW3191 and Fiat's 7-Z8260 are all written based on USCAR-2.

2) JASO D605-1996 Automotive Electronics Connector: The Japan Automobile Manufacturers Association has also developed a basic connector standard based on the comprehensive needs of Japanese car companies.

3) LV 124 Test items, test conditions and test requirements for automotive electrical and electronic components under 3.5 tons. This supply specification is prepared by representatives of the car manufacturers Audi AG, BMW AG, Daimler AG, Porsche AG and Volkswagen AG Compiled, this is also a joint enterprise standard representing the German automotive industry.

In fact, due to the actual situation of automotive connectors, we also choose larger ones rather than smaller ones, because there are actually more potential troubles caused by connector selection issues. Therefore, we not only refer to the standard system, but also select suppliers based on rankings.
