Some experts say that a conductive marker of high resistance can be successfully used with high humidity.
The glue hardens pretty quickly in devices. The optimum temperature for the models is 20 degrees. Store the device only in a dry place without direct contact with sunlight. If we consider professional models, then they use a high density node. In this case, the threshold conductivity coefficient is located at the level of 4.5 microns. These devices must be used only at positive temperature.
Circuit Board Devices
Models for contact boards are made with capacities of different sizes. Some modifications are made with toxic glue. It should also be noted that the conductivity of the markers starts from 2.5 microns. The maximum allowable temperature of the markers is 45 degrees. The writing nodes they use are of different series. The most common are modifications with a resistance of 55 ohms. The conductive marker must not be used in high humidity. The toxicity of the models is quite low. Before using the marker, be sure to shake it.
Models for panels
There are a lot of devices for panels. Modern modifications are made with high-density glue. Devices can be used at temperatures above 30 degrees. Experts say that models are not afraid of high humidity. The minimum allowable temperature of the markers is 0 degrees. Nodes for devices are installed in different series. Some modifications are made with elastic cases. Their line thickness is approximately 2 mm.
The conductivity coefficient for markers of this type is about 4.5 microns. In this case, the resistance index can vary greatly. If we consider inexpensive modifications, then they have a short holder. In this case, the tip is used with a small nozzle. When buying a modification, it is important to pay attention to the toxicity of the product and labeling of the adhesive. Do-it-yourself marker can be made with a short nozzle. The case is better to take from a regular pen.
Description of Ela Markers
Markers of the presented brand are distinguished by high density. The models use high-quality glue. Specialists use devices to work with various boards. Most devices are made with good conductivity. The usual model is made with a long nozzle. The water resistance parameter of the markers is at the level of 90%. In this case, the conductivity depends primarily on the type of glue. If we consider high-density modifications, their resistance index reaches a maximum of 45 Ohms. There are also many compact markers that will be very useful when repairing microchips.
Features of the Ela Medium marker
The conductive marker Ela (Medium 0 Ohm) is made with a short tube. The line thickness is not high. However, it is important to note good conductivity. Specialists also point to high-quality glue, which is located in a specially protected container.
The model is often used to lay electronic communications on the board. The coating itself is very elastic. Inside the pen there is a small ball. The track readiness is no more than 12 minutes. The glue in the device is completely non-toxic.
Keller Markers
Markers of this brand are appreciated for their high conductivity. Detectors are used with good sensitivity. Specialists use modifications on the boards of various devices. Line thickness in devices may vary. The glue in a device such as a Keller conductive marker is usually filled with a low density and has a long drying time. However, in this case, much depends on the operating temperature. The coating in the devices is elastic. Most models are made with short handles. The minimum allowable temperature at the markers is -10 degrees.
Keller marker features
Conductive marker Keller (7g) is great for microprocessors. It can also be used on boards of different conductivity. Glue in this case is used in high density. Experts say that the drying time does not exceed 10 minutes. The resistance in this case is at the level of 35 Ohms. It is also important to note that the model uses a high-quality handle. Before using the marker, be sure to shake it. The optimum temperature for use is 15 degrees. The density of the adhesive is not more than 50 mg per square. meter. Additionally, it is worth noting that the node in this modification will stand out in high quality. Keep the Keller marker in a dry place.
Modifications with a line of 1 mm
Modifications with a line of the specified thickness are suitable for the precise application of an adhesive conductive substance. Modern models are made with compact units. The resistance indicator is at around 45 ohms. The models use different pens. The minimum allowable temperature of the markers is approximately -15 degrees. It should also be noted that the devices differ in conductivity. If we consider the standard model, then her specified parameter is in the range of 2 - 4 microns. The devices are compatible with plastic and are safe for human health.
Devices with a 2 mm line
Devices of this type are actively used for applying electrical communications on microcircuits. Most models have excellent conductivity. Adhesive for modifications suitable for low density. If we consider a standard device, it has a capacity of 50 mg.
The solvent is used with a density of 20 mg per square. meter. The resistance of this type of device starts at 30 ohms. Conductivity markers are quite different. Many manufacturers make safety valve devices. It should also be noted that the maximum allowable temperature for markers of this type is approximately 45 degrees.
New models with 3 mm line
Devices with a 3 mm line are only suitable for channel cards. For models, as a rule, high-density glue is used. If you believe the experts, then the optimal temperature for work is 15 degrees. The covering ability in the devices is quite high. Many models are allowed for use in high humidity. However, in this case, you must carefully clean the surface of the board.
It is also worth noting that the minimum allowable temperature of markers of this type is approximately -10 degrees. The adhesive density for devices is at least 45 mg per kV. meter. Some models are made with host units. Cases they are able to boast a high coefficient of water resistance. In this case, the resistance is at least 30 ohms.
