New SMT line introduction

Electronics Forum | Thu May 18 12:32:57 EDT 2017 | dekhead

Evtimov, I believe you're taking a lot for granted here; "ordered" (to me) would means specs set (by whom?) and PO's placed. Getting it there, putting it together and making it build product is, I think, what Anthony is now tasked with... Is the eq

IPA versus Stencil Cleaning Solution

Electronics Forum | Tue Jun 13 15:03:54 EDT 2017 | mmjm_1099

For many moons, I have used IPA for our cleaning tanks within out DEK systems. Now we have a new engineering team and he would like to try a stencil cleaning solution (DEK PRO XF). Can everyone tell me there pros and cons of using each of these over

Programming for Pick & Place and AOI machines

Electronics Forum | Tue Jul 25 11:02:12 EDT 2017 | ks0707

Hello, I am a new comer and working for a contract manufacturer as an engineer. My company handles many prototype jobs from new customers, and most customers do not give us CAD file. We receive Gerber, XY and BOM from customers. So every single job

Programming for Pick & Place and AOI machines

Electronics Forum | Mon Jul 31 14:28:58 EDT 2017 | ks0707

Hi Evtimov and Phil, May I ask you how programming is accomplished at your side ? Do you have specific programmers dedicated to each P&P, AOI, Flying Probe, and Conformal coating machines ? Or one programmer handles programming for all machines per

JUKI vs UIC Pick N Place Machines

Electronics Forum | Fri Mar 09 01:49:46 EST 2018 | reckless

Which machine did you like more and recommend? My feeling is the Juki is simpler and easier by design thus making it easier to maintain. The GSM is very robust, highly over engineered making it more costly to keep going. Harder to work on for

How to install FBGA ICs on both sides of Flex boards with no stiffeners ?

Electronics Forum | Thu Aug 09 16:24:27 EDT 2018 | ks0707

Hi Thomas, Thank you for your posting and I agree with you that Printing is the most difficult one. BTW, after you ran the one side (let's say Bottom side), my engineer worries about the distortion of flex board because of the thickness. In that ca

Have any paper or data talking about "BGA Stencil design guideline for avoid bridge"?

Electronics Forum | Thu Sep 06 22:49:35 EDT 2018 | cmchoue

Dear davef, All of this are takling about how to improve release solder paste, Area ratio, aspect ratio...etc, but i want to learn the "When design BGA stencil which the safe air gap between solder paste in difference stencil thickness", this can he

Cost Per Placement

Electronics Forum | Mon Oct 15 15:29:19 EDT 2018 | emeto

You see, if you can optimize your product setup that will be the best. Back in the days, engineers used only standard values. For resistors for example I used to build boards having 100, 330, 470, 1k, 3.3k.....Sometimes that means you might end up wi

X-Ray Parts Counting

Electronics Forum | Wed Jan 08 13:03:05 EST 2020 | cyber_wolf

Yes, we ended up with VisiConsult. Technical support is A++ and I really like the simplicity of the software interface and the counting cloud. Anytime you run into a shape that will not count correctly, you take several x-ray photos and upload them
