10, test and visual examination: data and record after taking out the lamp bead test vulcanization inside U-shaped cup, with micro- sem observation
Whether abnormal lamp bead surface splits glue, and whether alloy wire blacks；
11, test summarizes: vulcanization front and back data will be made into table remittance on the spectrometer of a distant place with U disk copy vulcanization front and back data
Always, cured samples are attached in report.
Further, it to be reset before electronic scale use in the step 2, error is 0.5%；The irritant gas of sublimed sulfur
Taste, taking should select the place of air circulation or band to muzzle when sulphur powder.
Further, it is marked and remarks when being tested in the step 4, when test notices that voltage and current is chosen；It surveys
Examination mode is referring to distant place spectrometer working specification；Automatic integration is selected when electric current is less than 150mA；When electric current is equal to 150mA, use
20 integrals；When electric current is equal to 350mA, with 10 integrals.
Further, lamp bead is successively placed on label paper in the step 5 in order, indicates the time and name is protected
Keep data.
Further, oven temperature will keep 105 ± 5 DEG C of oven temperatures are higher need to wear gloves in the step 8, often
The primary decaying of hour test.
Further, oven temperature is very high in the step 9 need to wear gloves, be sure not when taking out sample at this time too close close
Vulcanizing tank avoids sucking sublimed sulfur.
Further, it when handling data in the step 11, successively copies data in table in order, it is logical to choose light
The data of amount calculate average value, compare the sustainment rate of luminous flux, record the lamp bead situation of micro- sem observation.
After above-mentioned technique, the invention has the following beneficial effects: one kind of the present invention can verify that LED product vulcanization effect
Experimental method, more true simulation client's test condition, reduce with the gap of custom test data, to meet client's need
It asks；Promote product quality；To promoting the market competitiveness, while terminal client being allowed to feel more relieved the product using enterprise.
Specific embodiment
Present embodiment the technical solution adopted is that: its operating procedure is as follows:
1, be ready to vulcanization need material: sample, label paper, tweezers, vulcanizing tank (U type bottle), electronic scale, gloves, mask,
Sublimed sulfur, spoon, beaker；
2, weigh: take 1G sulphur powder (literization sulphur) to be put into 25ML beaker (will reset, error is 0.5% before electronic scale use；
The irritant smell of sublimed sulfur, taking should select the place of air circulation or band to muzzle when sulphur powder)；
3, it places: U-shaped bottle (vulcanizing tank) center that 25ML beaker is put into 500ML (is slowly opened bottle cap and is carefully placed into beaker
U-shaped bottle center)；
4, it tests: first choosing suitable fixture and sample is measured, measure photoelectric parameter with tweezers clamping sample is upper in the distance,
Test data is kept, is fixed on label paper and (is marked when test and remarks, when test notices that voltage and current selects after having surveyed
It takes；Test mode is referring to distant place spectrometer working specification；Automatic integration is selected when electric current is less than 150mA；Electric current is equal to 150mA
When, with 20 integrals；When electric current is equal to 350mA, with 10 integrals)；
5, record: lamp bead (is successively placed with by the time of the name and serial number vulcanization that record sample in order with the name for testing people
It on label paper, indicates the time and name keeps data)；
6, it crosses Reflow Soldering twice: reflow machine being switched on and is preheated, booting and operation are operated referring to reflow machine operation guide；To
After Reflow Soldering indicator light becomes green, started Reflow Soldering.
7, be placed with: the lamp bead of experiment is put into U-shaped cup after testing data, lamp bead front upward, with label paper handle
Lamp bead uniformly adheres on U-shaped cup/lid centre.
8, enter oven cooking cycle: sealing Y 500MLY type bottle is put into 105 DEG C of ovens and stores 4 hours (oven temperatures
Keep 105 ± 5 DEG C of oven temperatures are higher need to wear gloves, the primary decaying of test per hour)；
9, it takes out: taking out beaker after storing 5 hours respectively and be put into and cool down that 25MIN(oven temperature is very high need to wear gloves at room temperature,
It is sure not too close close vulcanizing tank when taking out sample at this time, avoids sucking sublimed sulfur)；
10, test and visual examination: data and record after taking out the lamp bead test vulcanization inside U-shaped cup, with micro- sem observation
Whether abnormal lamp bead surface splits glue, and whether alloy wire blacks；
11, test summarizes: vulcanization front and back data will be made into table remittance on the spectrometer of a distant place with U disk copy vulcanization front and back data
Always, cured samples report is attached to above (when processing data, successively to copy data in table in order, choose luminous flux
Data calculate average value, compare the sustainment rate of luminous flux, record the lamp bead situation of micro- sem observation).
After above-mentioned technique, present embodiment is had the beneficial effect that
1, client's test condition is more really simulated, the gap with custom test data is reduced, to meet customer need；
2, the vulcanization experiment condition after changing is more harsh, and product will reach the standard that passes through of experiment, the design scheme of product and
The raw material of collocation will more rationally, to promote product quality；
3, can be to the quality-improving of enterprise product, to promote the market competitiveness by above-mentioned two o'clock, while allowing terminal client
The product felt more relieved using enterprise.
The above is only used to illustrate the technical scheme of the present invention and not to limit it, and those of ordinary skill in the art are to this hair
