Hello, I am wondering where I can purchase and read up on the specs for the proper solder flux pastes for Luxeon emitters. I notice in there aplication briefs they mention 380SR-flux gel and a few others but I no clue if that is a model number or wha

We use component BFU730LX and we have one problem. After reflow transistor base or collector lands are not soldered. Maybe someone have similar problems with this component? We tryed to change stencil pads (smaller , bigger) but problem is the same.

Here in this circuit LED is placed at the collector. i am with an impression that, IE=IB+IC. so it is better to keep at the emitter, right ? all the gain of the transistors are not utilized. What is the purpose of LED, placing at collector? Please e

You did not attach anything here. Transistor can be connected in different circuit(like common Emitter) and will use Collector current as output. Also Ic is about the same as Ie in value, as base current Ib is insignificant usually in uA.

Bert, Clean the emitter disk of the nozzle you use for this part. Set everything in the PD back to where it should be and set the "Lead_check_area" to 10. This will look at 10% of the end of the leads. This will help if the leads do not have even

There are two IR sensor (one for tipdown detector and other one for tipup detector) for each tip in each head. You should check infrared sensor for Head2 tip1, that cause may be by dirty between IR emitter and IR receiver. Just clean it and try to ru

We had a Mycronic tech in adjusting rings to get us within spec. He was saying the emitter/receiver board at the top and the tubes themselves can go bad. Between that and having weak latches, we're looking at a refurbished unit. But we're rocking a M
