I was wondering if anyone was using this machine to place 0402's and what type of 1st pass yield you were getting. I'm a little leary about the mechanical centering on such small parts. How is the feeder pick up position after it is taught? I have h

There is no set formula. You need to customize this number around your operation. Depending on how you account for: Capital Equipment Costs Utilities Building Costs Overhead services Consumables ( Flux, Paste, Glue, ...... ) Once you get the costs

Harry is correct. Like any process chemical it has to be installed and maintained properly. It is not hard to do but it is important that it be done correctly. After all it is easy to plug in a light but if you do not do it it will not light up. Doe

I can't see why it would be any different, You are melting the balls into reflow to the pad. In my opinion, paste is only useful in this situation to keep the part on the board during placement along with some planarity concerns in some instances.

What I mean by it does not work is after I moved the brackets I have about 4.5 inches from the end of the TWM to the conveyor point. None of our conveyers fit there all our Conveyers have about 6 inches in the front on the conveyer. Is there a differ

From technical point of view: it should not be a problem to mix Pb with Pb Free components soldered with a LF solder process. You have to take care about the max temperature allowed on your Pb components and make sure they can withstand the higher

Watch the solder profiles allowed for these caps. Most electrolytics cannot withstand high heat. Even RoHS compliant Electrolytics are often rated for peak 245C, 3 secs max, for example. Nowhere close to the 260C 10-20 sec you usually like to see.

Hi all, I'm working in Military Production and then, We have an exception about RoHS (LEAD FREE), but, because we use "normal" components, in this moments, a lot of components have LEAD FREE terminations, and we think that after of 1st July, we wo'nt

Density is an "implied" measurement to determine activity. Most flux suppliers can sell you a flux acidity (activity) measurement kit. I used one from Multicore a few years back. We used it once in the morning and once after lunch to monitor no-clean

We used an Alpha Metals No Clean Solder Paste on our products. However at 50% humidity and above, electric arching starts to appear across our y-cap, when a hi-pot voltage of 1500V is applied across. At 20% humidity this situation does not occur. Als
