clean process vs non clean process

Electronics Forum | Thu Apr 01 09:10:55 EST 2004 | cyclopsn

We are currently using non clean paste and non clean flux in our manufacturing process. But recently our customer feedback that using a non clean process might cause flux blockage in via hole area and potentially might burn or explode the boards over

clean process vs non clean process

How high a voltage? TV products use hundreds of volts on the vertical and horizonatal sync circuits. Historically, these consumer products were NOT cleaned. For your situation, contact your paste supplier.

There is no shortage of reasons to clean your boards. Soldering or reflowing your boards leaves �stuff� on them. This �stuff� is normally corrosive and conductive (some fluxes / pastes are more corrosive / conductive than others). In either case,

Hi Ken I'm not so sure about the voltage level but I'm dealing with backplane boards. Michael, Thanks for the information, I dont mind changing the process but I need to understand why I needed to do do. That is only my concern.

Really, if you start out from the beginning planning to clean the boards, then DON'T use the no-clean flux! The way that stuff is made, it leaves a hard, low-solubility residue that takes a LOT of effort to get clean. If you plan to clean, use a wa

what test methods can be use to verify that the cleaning process for SMAs with water soluble paste is sufficient?

By definition, no clean solder can be not-cleaned. The solder/flux are formulated to result in low ionic-contamination, hence, no cleaning. I have, however, always had at least one customer that requests their no-clean solder get cleaned. No-clean

Cleaning result can vary from paste vendor to vendor and even within product lines. You should check with your paste vendor for their recommendations. Your process, materials and equipment will also have a significant impact on your success. If you'

It depends on your product requirements. I have seen aluminium wire bonding operations in as high as class 100K clean rooms. These are the assembly areas for calculators. The best is class 10K clean room for wire bonding. You can go upto fine pitch w

Hi Rob, I must take issue with your statement �By definition, no clean solder can be not-cleaned�. All no-clean fluxes can be cleaned. Whether or not one cleans no-clean depends on a variety of factors. More than eighty percent of all post reflow
