Castellated Module Reflow Problems

Electronics Forum | Fri Jun 10 19:22:59 EDT 2022 | jdengler

Yes. We only do the side not under the component and do 25 mils if there is enough room. A solder preform is simply a block of solder that is shaped like a SMT component and comes in tape and reel. Most solder manufactures offer these. You can ta

I have some engine over load problems in the central reel, has it been identified that the external team misuses talcum powder for rubbers and many times we find talcum powder in the shafts, however will it be enough to cause the engine over load? Do

Reflow Oven SMT QUATTRO PEAK L PLUS

Electronics Forum | Thu Jul 14 03:16:18 EDT 2022 | acouto

Thanks for the feedback, I've been having some problems with the motor overload in the conveyor and central reel whenever there is cleaning by the external company. After analyzing I always find talcum powder and lubricant (it looks like cement) on t

What size panels for chain oven

Electronics Forum | Tue Jul 26 13:34:18 EDT 2022 | emeto

10x6 to 12x8 is ideal for most equipment. Too small panel is not good too for handling by humans and machines. 1.6mm you can use as and depanel on the router. 0.6mm you might need to run on SMT carrier, if you see warping.

New SMT Placement Machine - Hanwa,Juki,or Mycronics?

Electronics Forum | Mon Aug 01 13:14:49 EDT 2022 | emeto

I had Juki and Mycronic through the years in IL. Both had descent support and service. They are similar platforms by idea. Juki had smaller footprint and it was a very quiet machine. Mycronis is unbeaten in flexibility and changeover - great concepts

Component orientation

Electronics Forum | Wed Aug 03 07:29:03 EDT 2022 | pradeep14

Hi, We are facing the issue with Component orientation(Wrong orientation), during Proto build/NPI time in SMT for 1st board placement. We are not doing 1st board with STICKY board, directly placing the components with Paste board only. Pls suggest, H

Recommendation for Line for New Manufacturer

Electronics Forum | Wed Nov 02 17:32:11 EDT 2022 | proceng1

I would suggest finding a USED Samsung SM482 or similar. As far as flexibility, we regularly do work orders of less than 25 assemblies. In fact, we have an SMT line basically catered to low volume runs. We are in Pennsylvania, so we aren't local, but

Partially completed PCBA Storage

Electronics Forum | Sun Dec 25 09:51:54 EST 2022 | msirifat

Hello, We use OSP-finished PCB. One component (transformer) will be delayed (approximately 4 months) to getting in our hands. We want to partially complete the PCBA (both SMT & MI) in the meantime and later insert the transformer upon arrival thr

MPM UP2000HiE software versions

Electronics Forum | Thu Dec 29 18:44:36 EST 2022 | compit

Yes, there are two lengths. My MPM UltraPrint 2000 HiE has trays protruding from the machine about 15 cm, I think. I'll check with the company tomorrow to see if there are any numbers in the manual. I have a link to the part saved - maybe check it ou

Head in Pillow defects with memory components

Electronics Forum | Wed Jan 11 18:59:22 EST 2023 | agrivon

At SMT assembly level, the main HiP mitigation actions to consider should be increasing the stencil thickness/aperture sizes (typically in the 4 corners where warpage is maximal) + possibly reducing the reflow peak temperature as probably indicated i
