The100 Pa , implicating that the designed pastes are appropriate for screen as well as the array of pastes containing 50, 60, 70 and 80 with the functional phase stay inside the range of one hundred Pas, implicating that the created pastes are suitable for screen and stencil printing. stencil printing. measurements, VJ pastes had been applied using a needle dispenser onto the For current For present measurements, VJ cotton substrates. SMD 0805, 0 dispenser properly as get in touch with pads ready earlier on the pastes have been applied using a needleresistors asonto the make contact with pads preparedonto the make contact with pads substrates. SMD applied resistors cured for 0603 LEDs had been joined earlier around the cotton with previously 0805, 0 pastes and at the same time as 0603 LEDs C. Next, a drop of TPU for encapsulation was applied using a needle dispenser 30 min at 50 were joined onto the get in touch with pads with previously applied pastes and cured for cured for 50 . 30 min. Schematic is for encapsulation and 30 min atanother Next, a drop of TPU shown in Figure 1. was applied having a needle dispenser and cured for a different 30 min. Schematic is shown in Figure 1.Figure 1. Schematic of diodes/resistors mounted on textile substrate. Figure 1. Schematic of diodes/resistors substrate.two.3. Electrical Measurements 2.3. Electrical Measurements Resistivity was calculated around the basis of measured sheet resistance of layers printed Resistivity was calculated on the basis of measured sheet resistance of layers printed on polycarbonate layers. The final resistivity after 30 min curing at 50 C for VJ 60 was on polycarbonate layers.-6 final resistivity following 30 min curing at 50 for VJ 60 was 1.three The 1.3 610-6 m, 1.0 -6 10 m for VJ 70 and six 10-7 m for VJ 80. What’s worth 10 m, 1.0 ten m for VJ 70 and six 10-7 m for VJ 80. What exactly is worth mentioning, mentioning, just after 30 min curing at 90 C, VJ 70 resistivity drops to 7.two 10-7 m. Joint soon after 30 min curing at 90 , VJ 70 resistivity drops to 7.two 10-7 m. Joint resistivity might resistivity may well differ from layer resistivity. That is certainly why we decided to concentrate on joint differ from layer resistivity. That may be why we decided to concentrate on joint resistance and its resistance and its adjust following mechanical tests. transform right after mechanical tests. bending and stretching measurements were prepared around the samples for electrical, The samples for contact pads. Chains stretching measurements were ready on cotton Bomedemstat Histone Demethylase substrates withelectrical, bending andof five resistors in line were Tenidap Purity attached for the cotton pads. Before mechanical measurements, all the samples had been electrically speak to substrates with get in touch with pads. Chains of 5 resistors in line have been attached towards the speak to pads. Before mechanical measurements, all the LED chains were created measmeasured applying a Keithley 2001 multimeter. Also,samples were electricallyin the ured using a as resistors. identical manner Keithley 2001 multimeter. On top of that, LED chains had been produced within the very same manner as resistors. two.4. Mechanical Shear Strength Measurements 2.four.
