Has anyone else been experiencing this lately? We have had a rash of boards that come in properly vacuum sealed. We store them in the hot room until we are ready to build, and we get bubbles under the solder mask. We've had 4 different jobs, all di

You are a very confusing person, one minute you want to buy some cheap piece of crap and speed isn't all that important and now you want a Lambo! Different use cases will make different machines faster if optimised. Or for the rest of us they averag

It depends on what you mean by "going from....to....". If I just decided that I wanted to try a Type 4 paste on something that I'd been having problems printing, I'd probably just grab one (edited to add that we have a couple of re

Hi, We are using a 15mils to 5 mils step stencil with a metal blade. The 15mils area the surface is smooth and polish and in the 5mils area the surface is rough and porous because of the laser process. In the 5 mils area where there is no aperture t

Thank you both. We are using EP256 Solder Paste Sn63Pb37 no clean from Kester. I attached our profile as well as Kester's target profile. We used a populated demo board for the profile. We tested along the width, and was less than a 2c difference.

I think this probably depends a bit on what is in an ssa file (no idea personally)and how the machine you are moving to works. For instance if you have intelligent feeders than any data relating to where a feeder is loaded or the best place to put it

Hi Hearse, I currently use a MY600, with a AG Ejector which can place dots between 0.33 and 0.52 mm. The differences for a MY600 with placing small dots is down to ejector and paste. To be able to place dots as small as 0.25 mm, you would need an

I might answer some of your questions: 1 - in order to use old 24V feeders, Advantis needs 24V feeder kit installed. As far as I figured out, it's only 24V transformer and wiring, so I guess you can do it yourselves if the machine is not upgraded

Is the variation between markings human-detectable, or does the issue only crop up when you use a scanner? Different scanners can definitely have different results. Try a few models, and make sure you aren't using any damaged scanners. When you se

Pretty new SMT process engineer here. Context: we are using a MyData100 and using MYcenter software with it. Most package naming conventions only define outer area/foot print dimensions. However, I do not know of any convention for further package de
