SMT line expansion - new oven and selective solder | 22 February, 2020

Hey all,

I've made a post in the past about us expanding to a new space, but I wanted to do a new post with specific questions.

We currently have a DEK 265, Phillips Opal Xii, and a Heller 1500. Our main reason for expanding is to have a lead-free capable oven and a selective solder for through-holes.

I really would like to keep the cost of this expansion low, until we get additional lead free and THT jobs to utilize the new machines.

I will be getting the new equipment from the same used equipment distributor we got everything from before. The prices are a bit high, but the service we receive is worth it x100.

For the selective solder, there is an EBSO SPA400 that has a full lead-free pot for ~$10K.

The ovens we are limited as we only have 240V, and it seems the larger 8+ zone ovens are mostly 480V. Either a 2011 Vitronics Soltec XPM3i-820 for ~$20K or a 2001 Heller 1808EXL for ~$10K.

So basically I have two questions:

1) Thoughts on the EBSO selective solder? I eventually plan on getting both a wave and selective, but right now we have some double-sided boards, so we need the selective first.

2) Is the Vitronics worth a $10k+ premium over the older Heller? Of course, it will be a better oven, but with the same amount of zones, at the end of the day, it's just an oven?

Being able to save that money on the oven will allow us to add a second pick and place sooner, so it definitely helps to save costs. We do a ton of prototype and super small batch runs, so planning on a MyCronic/MyData in the future.

Thanks as always!
