Embedded lamination of thin film Nichrome resistors

The embed lamination procedure induces the high stress on the resistor and produces the high tolerance alteration. The embed lamination increases tolerance above 1%. The variation changes while the first lamination process may be caused by the surface stain or chemical and mechanical interaction between resistive layer and resin. In the separate tests a kiss lamination cycle was implemented while the embed lamination step. The kiss cycle ramps the press temperature to high priority to the applications of the final pressure. This cycle induced a smaller increase in the tolerance as compare to immediate simultaneous application of high pressure and temperature at the starting of the cycle.

The resistance values describe the change in the average values induced by the stress analysis. The 1 square, 100 ohm per square materials were laser trimmed to 120 ohm. The resistance of the Nickel-Chromium-aluminum-silicon alloy varies less than Nickel-chromium alloy. The resistance variation offered by nickel-chromium alloy to a lower value while the Nickel-Chromium-aluminum-silicon alloy resistance changes to a much higher value. These variations in the average value can be counted for through artwork recompense as stated by Wang et al. the variations in the tolerance as shown in the following table are not recompensed by the artwork modification.

Resistors are 1 sqaure, 100 ohm per square laser trimmed to better than 1%, 3 sigma tolerance. The analysis in every bunch of four are from left to right thermal cycles, solder reflow, relamination and humidity.

Conclusions

Etched resistors constituted of thin film nickel-chromium alloy layers are easily laser trimmed to a large tolerance. The laser trimming doesn’t alter the underlying glass/epoxy substrate. The Nichrome alloy with aluminum and silicon alters less in average resistance value and alteration in tolerance of laser trimmed resistos.

The laser trimmed thin film nichrome resistors embedded in FR4 epoxy substrate attain nominal variations by exposure to printed circuit board production procedure steps and to natural stresses. The minor changes state that laser trimmed embedded resistors offer the potential to be produced into a finished multilayer board with finished tolerance less than 1%.

Nichrome alloy PCB Process and prolong simulation

The tests conducted to simulate influences of PCB process and prolong functionality were Humidity test including 40oC, 95% humidity for 240 hours. Second step includes solder reflow: conducted per EIA/JECDEC 22-A112-A with preconditioning at 30oC, 60% RH for 192 hours then conduct the convection reflow for 10 times at the highest temperature about 220oC. Third step includes thermal cycles: MIL-STD -883, method 1010.7, condition C-65 to 150oC, 1000 cycles and fourth step includes repeated epoxy FR4 lamination cycles at 360oF, 300 psi for 100 minutes. Before the rest, the resistance was calculated manually on the trimmed resistors with the multimeter utilized to measure resistance after the test. The average value from a panel was in close proximity with the average from the trim device. The nominally broaden distribution of values was noticed from manual measurement than that of full-kelvin probe measurement in the trim equipment.

Before the stress test, the nichrome alloy resistors were embedded in a 140oC, Tg FR4 glass/epoxy. The embed lamination step used two sheets of FR4 prepreg, 1080 glass, atop the etched, trimmed resistor. A Tedlar release sheet was kept among the prepreg and the stainless steel press plate. The lamination was done at 360oF, 300 psi, for 100 minutes. The dielectric thickness atop the resistor layer subsequent pressing was 5 mils. The resistance was calculated after the embed lamination and after the stress test. The electrical link with the inserted resistor was made by grinding through the laminate with a Dremel tool to copper contact pads. The pads were big and well eradicated from the resistor to decrease the mechanical stress to the resistor and contributions to alterations in the resistance. The data analysis of 11,076 resistors was simplified by calculating 1 square trimmed resistors.

The variation in tolerance of the resistors arrayed throughout the panel and from panel to panel produced while the analysis is described in the following table:

The stress tests induce a minor alteration in tolerance, normally less than 1%. The 100 ohm per square NiCrAlSi alloy functions specifically well, varying less than 0.25% in all the tests. It is a component due to the goof thermal stability of nichrome alloy. The negative values in the data showing the tolerance seems to be enhanced subsequent the stress test is likely because of nominal measurement imprecision.

Solid epoxy laminates are utilized in the electronic applications that need outstanding chemical, mechanical and thermal stability. These attributes add to the high functionality of the inserted nichrome alloy resistors. Nominal x-y axis expansion adds to the better functionality in the 10X reflow and the thermal cycle analysis. A region of the stable functionality is supposed to be because of the competency of the glass or epoxy to be an influential plotting compound for the resistor because of tendency to block intrusions of humidity and block transfer of thermo- mechanical stresses to the covered resistor.

Perforated Metal pattern specification

End patterns of perforated metal

On staggered pattern perforations, the end patterns of perforated metal are finished or unfinished on the base of tooling. An unfinished end pattern is standard, although a finished end is available as a non-standard material. Unfinished end patterns are standard on some staggered pattern perforations, meaning the hole pattern appears incomplete at the end of the sheet.

Finished end patterns are non-standard on the most staggered pattern perforations, meaning the hole pattern is complete at the sheet end.

Margin:

Margin defines the distance from the sheet edge to the first perforation along the same dimension. No margin refers to the last row or set of perforations extending off the sheet or plate.
