MicroFab Product FAQ - FAQ

As an excellent equipment supplier for the inkjet printing (Inkjet) industry, MicroFab has done a considerable amount of work on the technical parameters and customization of its products. Check out the details in the solution and technical support for the application of the device .

Here are some common questions.

Q1: Technical principle and specific parameters of MicroFab nozzle?

A1: The principle of inkjet printing technology adopted by MicroFab technology. The core component of the MicroFab nozzle is composed of a tubular glass tube surrounded by a piezoelectric actuator. One end of the capillary glass tube forms a nozzle (20 to 120 microns in diameter, other dimensions need to be customized). When a voltage pulse is given, the piezoelectric actuator generates a pressure wave through the glass into the liquid through the piezoelectric effect. At the nozzle, the pressure wave accelerates the liquid, forming a small liquid column that leaves the nozzle and then breaks, forming a droplet that flies into the air.

Nozzle diameter: 20 - 120 μm

Single drop volume: 5 - 500 pl

Volume change rate: about 1%

Applicable viscosity range: 1 - 20 mPas (20 cp, no heating)

Other (20cp after heating, up to 240 °C)

Produce drop rate: 0 - 20000/s

Maximum productivity: 10 μl/s

(★Depends on the fluid used)

Q2: How many specifications does the MicroFab nozzle have?

A2: According to the literature "polymer electroluminescent display based on inkjet printing technology [J]. Peng Junxi, Liu Nanliu, Wang Jian. Liquid Crystal and Display. 2009, 24(3): 311-321." Description: "Micro Fab The print head developed by the company has single-hole injection and can be independently controlled. Made of porous jets. Single-hole injection is easy to operate and relatively low in cost. It is generally used in the laboratory for pre-development work. Each jet of the porous jet printhead developed by Micro Fab can be operated independently (independent control circuit and separate solution communication vessels, similar to a set of single-hole jet printheads), which are mounted in digital control On the rotary table device, by using the corresponding software to control the rotary print head to match the substrate pixels to be printed, a multi-jet print head can be used to prepare devices of various specifications without changing the spacing between the injection holes. The devices are mostly used for the evaluation of new materials in the laboratory and the development of display devices for new structures. "

According to the above literature, Microfab's products are very suitable for research institutes and industrial enterprises R&D departments.

At the same time, the above-mentioned single-hole or multi-hole nozzles have diameters of 20-120 μm, which are available for users to choose, and a system can be compatible with nozzles of various diameters.

Q3: Why choose Microfab?

A3: First of all, Microfab has 22 years of experience in the Inkjet industry and has extensive experience with the applications involved. The breadth of the range of applications involved is unmatched.

Secondly, MicroFab's equipment is simple to operate, clear in structure, and customizable, making it the best choice for scientific research;

In addition, MicroFab's nozzles are available in a variety of sizes (different in diameter or number), allowing users to more easily select the device that meets the application rather than allowing the user to do research according to the requirements of the device;

In addition, MicroFab can save costs for customers, usually in the use of these devices such as microchip laboratory production, DNA testing or OLED material production, the cost of these reagents (liquid) is quite high, MicroFab for each nozzle There is a separate controller, which saves costs by maximizing reagent savings;

Finally, MicroFab's design for individual nozzle control allows for more convenient and accurate on-demand printing (DOD).

Q4: Can I install multiple nozzles on the Jetlab4 series at the same time?

A4: The Jetlab 4 xl series in Jetlab 4 is a four-channel nozzle that can be installed with PH-46. This four-channel nozzle can solve the requirements of successive spraying of different liquids. Here and you explain, the simplest jetlab 4 can not install this four-channel, xl series can. The Jetlab 4 series has a total of four products, Jetlab 4, Jetlab4 xl, Jetlab4 xl-A, and Jetlab4 xl-B. The price is sequential. If you want to select four channels, at least the Jetlab4 xl type is used.

Q5: Can JetLab print BMP bitmaps? Can I scale the print?

A5: Jetlab can complete the printing of bitmaps. For zoom printing, it can be done with graphic editing software. After editing, print again and the effect is the same. One thing to be stated here is that Jetlab's vector printing has more advantages than bitmap printing. Our experience is like this. Using inkjet for bitmap printing requires the horizontal and verticality of the X and Y mobile platforms. Well, the positioning accuracy of the bottom plate machinery is very accurate, otherwise there will be a step phenomenon at the edge of the print, that is, the printed line appears jagged. The biggest advantage of Jetlab is that it can print both bitmap and vector. Other similar products can't do it.

Q6: Can JetLab measure the line width and the distance between the print line and the line?

A5: This function requires customization, but it is difficult for measurement because we measure it optically, because the substrate and printed material optics often occur in view of different substrates and printed materials. The contrast is very low, affecting the results of the measurement. It is precisely because the process of the experiment may have a lot of printed materials and bottom plates, so sometimes the accuracy of the measurement will be compromised.

Q6: Does Jetlab4 have a rotary table for printing?

A6: There is no physical rotary table, but there is a rotating proofing software, so there is no need for a rotating base. Rotary printing can be achieved by setting a reference coordinate system in the software.

Q7: Can I use CCD to locate feature points?

A7: The bottom plate and feature points can be proofread. The corresponding feature points can be selected for calibration by passing through the CCD.

Q8: Can the backplane be repositioned?

A8: Yes, the backplane can be repositioned very quickly.
