Hi. Have an older 1809EXL that was purchased new and has sat idle for years with 270 on hours as of today. After days of testing, unable to melt fresh paste from Loctite (SAC305). The root cause after the investigation is due to one of the 2 TDM modu

DEK conveyor belt

Not as straightforward a question as you might think... due to the multiple rail systems (at least 4) used on Europa. But what you seem to be describing is the single stage conveyor, which uses same belt as used on the GSX, and majority of Horizon /

Solder balls on solder side!!

If we were talking about a single board problem, we�d be thinking about the laminate, but since you imply the problem is broad-based across multiple assemblies, consider the following machine parameters: * Crank-up preheat time / temperature to driv

Spray Fluxers

Electronics Forum | Mon Aug 22 11:49:59 EDT 2005 | pjc

Fixed spray head performance depends on board width. If you are looking for complete top-side hole fill, the flux penetration into the lead-hole will be more in the center and less on the ends because of the fan pattern spray. For board widths over 6

Reflow oven reliability?

Electronics Forum | Fri Sep 07 16:53:37 EDT 2012 | burb1999

We have Heller, 1707EXL now. It has a removable support for the mesh conveyor that just pull out (clipped in). Had an Electrovert and they were bolted on and very tuff to change out. The oilers Im not sure I care for though,they have a metal rail t

Question about Oven Profiles

Electronics Forum | Mon Mar 26 19:22:22 EDT 2018 | tey422

First of all, shouldn't allow SMT operators to edit/create recipes, only grant access to the well-trained only. You will put yourself at risk if you don't have good process rule of oven recipes. Newer oven models should come with software that has m

No such thing as a Compact Reflow Oven?

Electronics Forum | Thu Sep 13 15:09:07 EDT 2018 | reckless

So it took me a few months to figure out the compact reflow oven market. I bought the following ovens: Heller 1500EXL Essemtec RO300FC-C - QTY 2 DDM Novastar Gold Flow - Desktop DDM Novastar 1800HT - Conveyor Zevatech 5 zone oven T962C benchtop ove

MPM Up2000 and SMEMA

Electronics Forum | Mon Sep 12 09:26:00 EDT 2016 | awhite

Our MPM Up2000 HIE is having a communication problem with any upstream machine we place in front of it...i.e. conveyor, board loader, etc. It all started when we removed a conveyor from inbetween it and a board loader, and hooked those machines up di

I think your solder mask is a partial cause of your solder balling. Additionally, adjusting some machine set-up parameters may also help. 1 If we were talking about a single assembly problem, we�d be thinking about the laminate, but since you say t

Selective moving pot vs fixed pot

Electronics Forum | Thu Jul 10 13:34:43 EDT 2008 | rwyman

We have a Vitronics mySelective machine (model 6749, or "the Fat Bastard" as we affectionately call it). It's configurable with various combinations of "select wave" and "multi wave" pots. Ours has one of each. The "select wave" is for the most pa
