Map Sorting of Package LEDs onto frames

ASM MS899DLA is a high speed map sorter machine especially designed for handling ceramic based LED with dome lens. Input is a cassette of film frame carrying the package LED on the film frame.

The reason is that the LED has to have tracebility up to die level, if that is not placed on mylar in a mapped format, there is no way to trace the LED to the die batch form the Wafer.

The up stream process is either a Panel tester using Integration sphere or a Package LED tester AS899 (ASM’s).

MS899DLA is a fully automatic map sorter machine with Auto cassette handler and max.
120 Bin grade of film frame each represent one specified Bin grade of binned LEDs.

There is a wafer bar code reader to read the lot bar codes or using 2D matrix code camera to read, identify and pull pout the right wafer map from the network for the film frame in process.
The UPH is typically 4,200 for 3mm x3 mm package LED with dome lens.

The Collet is designed not to have any contact on the surface of the dome to minimize scratches.
Typical Cycle time is 430ms for 3 mm x 3mm x 1.6 mm LEDs.

This machine is commonly used for many LED Big players for sorting out their package LED onto 100 bin grades.

Downwards process is to pass the binned wafer on Taping machine LPT08 for putting the package LED onto tape and reel.

Not too long ago, Globe Tatoo is equivalent to Globe Broadband branded as 'hip.' Now, Globe Telecoms rebranded it to cover a myriad of services central to the new Globe Tattoo sim.In a recent bloggers' launch at M Cafe and Handle Bar in Makati, Globe introduced the Globe Tattoo Sims, Youniverse, ImmortalTXT, and Surf All Day services.Globe Tattoo SimsIt brought the modern, hip, and rebellious

Yike Bike

The Yike Bike has today been wooing Europeans on German streets as its developers try to sell their new mini-farthing cycle to the European market.

Inventor Grant Ryan said he hoped its European debut would spark interest ahead of a major trade fair later this week.

The New Zealand carbon fibre Yike Bike can run for 10km after a 30 minute charge, 10Kg in weight , install in 15 Sec, easy to control, LED lighting design. A green toy for us? We have to reserve for one. Price? May be in the range of USD$5,000.

My Friend Leo is the No. 1 HK people on the order reserve List.

I am sure that there will be newer design from China selling at about USD$900 in April 2010.

Let’s see

Small and Big Chip Design and efficacy

Blue represents the optical power and Purple indicates the Electrical power

LED efficacy is 25%, 75% of the electrical energy will be converted to heat energy, however when the smaller LED is having smaller power with say 20mA of current passing through, they efficacy could be as higher 55%.



There will be 55% of optical power Lumens output and 45% of energy will be dissipated as heat energy. however when the current increased say to 350mA, the efficacy can be about 25%. 75% of the electrical energy will be dissipated as heat energy which is a waste!

So we can see that there is a big different in LED design on the East and the West.
As most of the LED in Japanese Maker are using comparative small chip 0.2mm x 0.2 mm to 0.29mm X 0.29mm current such as 20-50mA range by using a number of small Chip to create more optical Lumens. Such design in fact as much a higher energy conversion than driving the LED at much a high current say 350mA or more, as when chip is bigger current .


But most of the US and or European design will be using 350mA as standard current reference for driving their LED. Such as K2, Rebel, XRE, XP, Oslon...

As for Japanese design such as Citizen, Sharp, we can see that they ar using a lot of LED from 10-20 pcs each of them are driving at smaller current, there will be a lot of manufacturing process as there will be multiple bonding on Die bonding and Multiple wires.


But the advantage is better energy saving, an some of them are connected in parallel, if there is one strand of LED chain is failure, there are still having some of the LED strands continue to light up. So as a reliability sense that is better. Whereas the other European Design will be black out of the LED is failed! So there thermal management of the current UHBLED will be an important engineering challenge for most of the LED players using big chip say 1mm x 1mm or bigger.

As we know if we have the best chip on hand, the final product reliability will be much depending on how low we can maintain the Junction Temperature. In any case we should design such a way to have a lowest Junction temperature of the Chip. Say if you can have a room temperature junction temperature, that is a dream case. And if you can maintain the Junction temperature at 85% m that is very good already, in worse case the junction temperature such not be higher than 125 Deg C.

As what highlight before if the temperature of the Chip is lower the life tine of the LED will be increased. Say form Rebel specification sheet if we can reduce 5 degrees from Junction temperate of 135 Degree C to 130 Degrees C, the life time of the Reel will be increased by 18,000 hours!!

If one day we can have a say Copper bas material and a very good of bonding connection material such as Solder (lead free is preferred) the Bond Line thickness is properly optimized for best CTE between the chip say EZ1000 and the Copper material. I think that is a very good design for low Junction temperature, as Copper is very good at heat energy conduction, and it is of low cost as comparing with AIN or Al2O3 ceramic substrates.



That can be a powerful LED… and if we can have very high efficacy Phosphor material and a good design of Lens, we may be able to create s very efficient LED with High Efficacy, good thermal conductivity, low cost as Solder is cheaper than Epoxy, or gold tin Eutectic process. However, the only concern is how good that it could sustain the reflow temperature say 260 deg C for two times. Will the Solder cause any delamination of the LED and the Substrates?
