Conductive markers are used for laying electromagnetic communications. As a rule, they are used on microcircuits and panels. Devices differ from each other in conductivity, resistance and thermal stability.
Recently, a conductive marker with an elastic coating has been very popular. The writing nodes in the devices are used in different series. Solvents for modifications are made of a certain density. When buying a device, it is important to pay attention to compatibility with contact materials.
Low Resistance Conductive Devices
The low resistance conductive marker is made with special clamps. The line thickness in the devices is approximately 1 mm. There are also models with compact bodies. Glue for them is refilled through the container. Modifications of this type, as a rule, are used to work on controllers. The drying time of the adhesive is approximately 15 minutes. It should also be noted that there are devices with toxic elements. Their nodes are used in different series. The threshold conductivity coefficient averages 5.5 microns. Some modifications causeallergies.
High resistance patterns
High resistance conductive ink marker suitable for PCB. Models of this type are made compact holders. Inside the tube is a small ball. Additionally, it is important to note that there are devices with large capacities. Glue is used with a conductivity of 44 microns. Some experts say that a conductive high-resistance marker can be used successfully in wet conditions.
Glue hardens pretty quickly in devices. The optimum temperature for the operation of models is 20 degrees. Store the devices only in a dry place without direct contact with sunlight. If we consider professional models, then they use a high-density knot. In this case, the threshold conductivity coefficient is at the level of 4.5 microns. These devices should only be used at positive temperatures.
Contact board devices
Models for contact boards are produced with containers 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 marker temperature is 45 degrees. They use writing knots 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 a marker, it must beshake.
Models for panels
There are a huge number of devices for panels. Modern modifications are made with high density glue. Devices can be used at temperatures above 30 degrees. Experts say that the models are not afraid of high humidity. The minimum allowable marker temperature 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 indicator 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 the labeling of the adhesive. A do-it-yourself conductive marker can be made with a short nozzle. The body is better to take from a regular pen.
Description of Ela markers
Markers of the represented brand stand out with high density. The models use high quality glue. Specialists use devices to work with various boards. Most devices are made with good conductivity. The regular model is produced with a long nozzle. The water resistance parameter for markers is at the level of 90%. In this case, the conductivity depends primarily on the type of adhesive. Considering modificationshigh density, their resistance index reaches a maximum of 45 ohms. There are also many compact markers that will be very useful when repairing chips.
Features of the marker Ela Medium
Conductive marker Ela (Medium 0 Ohm) is produced with a short tube. The line thickness is low. However, it is important to note the good conductivity. Experts also point to high-quality glue, which is in a specially protected container.
The model is quite often used for laying electronic communications on the board. The coating itself is very flexible. There is a small ball inside the handle. The track readiness time is no more than 12 minutes. The adhesive in the device is completely non-toxic.
Keller markers
Markers of this brand are valued for their high conductivity. Their detectors are used with good sensitivity. Specialists use modifications on the boards of various devices. Line thickness may vary between devices. The adhesive in a device such as a Keller conductive marker is typically low density and has a long dry 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 for markers is -10 degrees.
Features of the Keller marker
Keller conductive marker (7g) is great for working on microprocessors. Also hisit is allowed to use on boards of different conductivity. Glue in this case is applied 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. In addition, it is important to note that the model uses a high-quality handle. Be sure to shake the marker before using it. The optimum temperature for application is 15 degrees. The density of the adhesive is not more than 50 mg per sq. meter. Additionally, it is worth noting that the node of this modification will stand out with high quality. Store the Keller marker in a dry place.
Modifications with 1 mm line
Modifications with a line of the indicated thickness are suitable for precise application of the conductive adhesive. Modern models are made with compact nodes. Their resistance indicator is at around 45 ohms. The models use different handles. 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 its specified parameter lies in the range of 2 - 4 microns. The devices are compatible with plastic and safe for human he alth.
Devices with 2 mm line
Devices of this type are actively used for applying electrical communications on microcircuits. Most models have excellent conductivity. Adhesive for modifications is suitable for low density. If we consider a standard device, it has a capacity of 50mg.
The solvent is used with a density of 20 mg per sq. meter. The resistance of devices of this type starts from 30 ohms. Conductivity markers are quite different. Many manufacturers make devices with protective valves. 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 3mm line are only suitable for channel cards. For models, as a rule, high-density glue is used. According to experts, the optimum temperature for work is 15 degrees. The covering power in the devices is quite high. Many models are allowed to be used in high humidity. However, in this case, it is necessary to carefully clean the surface of the board.
It is also worth noting that the minimum allowable temperature of this type of markers is approximately -10 degrees. The density of adhesive for devices is at least 45 mg per kV. meter. Some models are made with wired knots. Their cases are able to boast a high coefficient of water resistance. In this case, the resistance is at least 30 ohms.
