Problems solved by technology
However, the control system of the power signal has the following problems: the LED is directly fixed on the substrate by means of conductive silver glue cold welding, resulting in the need to remake the substrate when replacing LEDs with different light wavelengths, which increases the production cost
[0003] The above problems lead to the complex operation and poor portability of the power supply circuit system of the transmission electron microscope in situ light-electric sample rod, which has caused great obstacles to its mass production and maintenance.

Abstract
The invention discloses a manufacturing method of a detachable light source substrate. The method comprises the steps of 1, etching a welding groove in a copper sheet to obtain a metal welding seat; welding the two ends of a 0402 SMD LED in the welding groove to obtain an LED welding seat; 2, etching grooves and screw holes in the side surface of a sapphire blocking sheet etched with through holes, washing, drying and cooling; 3, wrapping the sapphire blocking piece with tin foil paper, and sputtering gold ions in the exposed area to form an electrode and a wire; and 4, embedding the LED welding seat into the groove of the sapphire blocking sheet, and fixing the LED welding seat by using screws. The manufacturing method is simple in manufacturing process, and the manufactured light sourcesubstrate is small in size, low in cost and good in portability.
Description
technical field [0001] The invention belongs to the technical field of an in-situ photo-electric sample rod in a transmission electron microscope, and particularly relates to the preparation of a detachable light source substrate of an in-situ photo-electric sample rod for a transmission electron microscope. Background technique [0002] The transmission electron microscope is a microscopic instrument that uses the scattered signals generated by the interaction of incident electrons with the nucleus and extranuclear electrons of the sample. Through the transmission electron microscope, high-resolution micrographs, electron diffraction patterns and electron energy loss spectra of the sample material can be obtained to characterize the microscopic morphology, crystal structure and chemical composition of the sample. Due to its superior performance such as high magnification and high resolution, it has been widely used in fields such as virology, material science, nanotechnolog...
