I'm assuming these are two leaded axial components. GPD Global makes fluid dispensing and component prep equipment. Component leads can be formed (or bent) in order to provide some resistance in the hole during insertion. This should prevent the comp

Electronics Forum | Tue Jul 19 10:28:21 EDT 2016 | mrk

What kind of oscillator are you placing (Manufacturer part #)? I do not believe that oscillators fall under the "chip component" category. Even if they did, most all SMT oscillators that I have come into contact with have 1 sided terminations on the

Flexible Circuit Board Finish ENIG or Hard Gold?

Electronics Forum | Thu Aug 25 11:53:12 EDT 2016 | shawn_halo_1

Sorry if I was not clear. We have a Flex Circuit Board that is ENIG Finished. There are two connectors that are SMTd to either side of the Flex to connect to other PCBs within the system. Then, we have conductive rubber contacts that are press fit on

Help understanding something about stencil orientation when printing

Electronics Forum | Tue Nov 08 12:05:57 EST 2016 | aemery

Lachrymal, Where are you getting that from. Let me keep this simple because there can be so many variables in modern printing, some you can control and some you can't. Unless you are designing your own PCB's where you can decide how to orient the co

We are currently experiencing with our SMD Solder > Reflow Equipment on Shooting-Up Zones (Zones > 3,4,5,7 & even Cooling Zone). PV exceeds about > 5-10 degrees with the SP. (ex: SP=140deg, actual > PV = 145deg & higher). Our equipment undergo a

Conformal coat material dispensed through epoxy needle?

Oh yeah, so we have a auger valve similar to that on one of our other machines that we use for dispensing SMT glue, and solder paste also. We have a conditioner that we flush it with at EOD when in use, then we just let it sit idle with the condition

What is the QFN or Device Voiding Levels Needed for Automotive Industry for Power Devices for Electric Vehicles?

Electronics Forum | Tue May 01 20:40:38 EDT 2018 | sarason

In the past I have worked on 600 Amp FET Blocks. The rule was no voids. The circuit board would be heavy copper. 4 times normal plating time. Not particularly high resolution on the board say 20 mils. To help with the heavy plating. The boards were t
