In theory you are right, but the camera CCD chip has only small squares as pixels. The edges of the circle lit the pixels only by a certain percentage. In order to find the edges, you will have to use sub-pixels or greyscales. A circle is also prone

My snmall company out-sources all of it's SMT assemblies. We do through work and have dome rework experience with SMT. All of our assemblies are built to "IPC610 Class II". We currently have no one trained to inspect to this standard. What is a pract

we use A EKRA X5 it can use A pad our the fiducial I generaly use A pab becuse most of our stencil don't come with the fiducials on them and our boards our HASAL and the fids our domed most of the time the smt pads work better for me

Hi, This is for a Universal GSM1. Is there a way to make a nozzle rotate to the same point before picking the next component up. It is because we are trying to pick & place a rectangular component (Luxeon Rebels) with a rectangular nozzle. The nozzl

yes, we are also picking it up on the flat part of the component. So we won't damage the dome. Just as discribed on the assembly and handling data sheet. Because the component is picked up out of the centre, it gets instable when picking it up out of

You won't have 2 mil height because the solder doesn't remain brick shaped. It's a dome. In the past I tried doing some calculations using the formula for the volume of a spherical section and also tried using a simulation program that accounts for

Hi all, We are having a lot of trouble with mis-pick trying to place silicone dome LEDs(3535 package) It seems that the silicone of the LEDs is sticking to the side wall of the carrier tape pocket. The vacuum nozzle would normally suck up the led an

Hello, You can also use SD 218 -40 from HEP This is the Part who EKRA Company used After EOL from the HF The EKRA-Part.Nr. Is 5340000133 Its to use for 2x T8 , 18 , 25 36 W Or if you find Dome Times EKRA has used Quicktronic del Luxe HF36 for 2x 36

I had the same question. We have custom nozzles made by Count on Tools. I believe we found urethane works the best for the silicon domed LEDs. Have you slowed the feed rate down on the feeder? Also adjust the top tape to the back slot on the feeder.

Electroplating [electrolytic] and dipping [HASL] are the two methods for applying solder coatings to features on boards. Disadvantages of electroplating lead / tin are: * "Weak knees" created at the edge of plated through holes. [I used to get weak k
