The price increase of electronic components such as MLCC has not stopped. In recent years, driven by the development of electric vehicles, industrial control and other industries, the demand for MLCC products has increased rapidly. However, the overa

In our reflow oven it has pins which move at the predetermined speed to move the pcb through the various zones in the oven. The forward row of pins is fixed along the front of the oven. The rear set of pins is adjustable per the width of the pcb. We

There is no formula out there that chooses a model for low volume high mix. Every oven can manage the throughput, which leaves us with cost, servicing, flexibility and reliability. Ersa Pros: Longer heated length than the ovens I am comparing it t

Sorry I can't really answer any of your questions, but I'm curious about your idea. I've done vacuum drying of implantable medical components (made mostly of a proprietary bio-absorbable composition) but never electronic components. You're right to

We have been experiencing an issue with solder balls coming out of wave, both RoHS and 63/37, no clean process. It has been determined that a reduction in flux has all but eliminated the solder balls except for where we need to use board stiffeners a

Hi Phil, thanks. I am successful using the same connector on small thinner boards 2-2.5kg) i cant make it work, tried all kinds of profiles with vapour phase but to no avail. Yes you read it right 4.3-6.3mm pcb thickness and 2-2.5Kg. And it is 44 lay

There are two areas that are important when discussing cooling rate. One is the rate thru the liquidus, where a fast rate produces small grains in the metal and a slow rate results in larger grains. Although smaller grains are stronger normal SM

I want to avoid peoples preferences as they will differ and will not be a deciding factor. A heat gun will introduce risk to surrounding PTH components and having to add protection for those, will limit any gain in productivity. There is no question

Hi, 1. do not use flux-cored wire- the smell is bad and flux will evaporate anyway at the time of solder wire melting. 2. as suggested use solder bars, something like this: https://smtnet.com/company/index.cfm?fuseaction=view_company&company_id=39635

We need to be careful with product to avoid introducing a new failure mode, namely corrosion and dendrite growth, especially those running no clean processes! In addition to heat (reflow, wave and some selective soldering processes) killing the vi
