Suppliers have improved the utility and quality of OSP [organic solderability preservative] solderable surface protection over the years. Be cautious reading too much into older SMTnet [and web in general] conversations about handling OSP. When prop

There are several things to look for in a compliant tooling system 1. How much force per pin is required to lock the pins in place? This is especially important since you will be multiplying by the total number of pins on all modules. 2. Is ther

I hope to get some feedback here. I have a SMD connector that reflow-solders quite poorly (I guess solder paste or profile issue). On the X-ray I see strange bubbles, does it mean there are voids under pin? Generally I am not satisfied with the sol

Well, not really... the index does not say much by itself, as you say, you can improve your cycle time by 5% but if you don't update the product rate in your calculation, then you're not providing accurate data so your performance is going to be high

Hello thomas31, When we did our equipment evaluation, we looked at all of these systems with the exception of Goepel. My team and I thought that the image quality of the Mirtec machine was by far the best of any of the other vendors. We also found t

Change times for the Rheo pump are probably a little slower than just swapping blades. You have to hook up the sensors & air lines,remove the bottom cover + charge the pump to get it to operating pressure before you can print. I would guess that if y

In a perfect world, the machines would be maint."guys" for the automation machines. Think "closed loop" system. Anyway, getting back to our reality job, we are still game for automation to improve thru'put, quality, reduce problems. The focus here
