Tantalum caps “popcorn”

Electronics Forum | Sat Apr 27 10:43:25 EDT 2019 | smith88

I have read this I guess the question I should be asking is what have you done when finding these? IPC says it enters the body so it is a defect many in my group feel it should not be because they are not hermacticaly sealed anyway. I am needing thou

You sound like me lol. Champagne taste on a beer budget. People like the CP's because they are work horses that rarely break. You do however need a technician that isn't a goof-daddy to keep her tuned.

How to reduce solder joint voids of LED without using vacuum reflow?

Electronics Forum | Tue May 07 10:13:06 EDT 2019 | cyber_wolf

I have personally never seen a reflow profile change reduce voids. We have invited "experts" in to demonstrate this claim. They were unable to.

Squeegee Blade selection OEM? Coated?

Electronics Forum | Fri May 10 16:29:32 EDT 2019 | cbeneat

The only difference I've noticed going from OEM to after market/coated is, as a maintenance tech I don't get as much complaining from the line operators about the condition of their blades once we switched. We buy from Transition Automation.

Profiling for Pb-free HASL

Electronics Forum | Mon Jun 03 13:10:35 EDT 2019 | gregoryyork

We recommend a ramp soak spike profile for HASL finish, so everything gets nicely heated during reflow, we soak around 180C and peak at 245- 250C and don't have any issues as long as the levelling isn't too peaky.

Machine Leveling

Electronics Forum | Fri May 10 11:06:25 EDT 2019 | tey422

First of all, you would have boards frequently being stuck in between inline machines. In order for the best inline setup, all the machines should be properly leveled to have smooth transport from start to finish.

PCB bent due to mechanical force

Can we bent a PCB using mechanical force ?Will the PCB come back to original condition or it will be bent forever after the mechanical force is removed from the pcb?

PCB bent due to mechanical force

It would kill the component on the opposite side, be careful to bent a PCB especially with component installed. Be sure the bent warpage is no higher than the component permitted or not high to cause de-lamination.
