Currently in our facility we store used and discarded flux residues from the wave solder machines in 50 gallon drums. These drums are picked up and disposed of by an outside contractor. During a recent audit we were cited for not having the drums

We are having problems removing the flux residue from our boards in our batch cleaner. We use Indium SMQ92J which I hear is notoriously difficult to remove. Can anyone suggest a similar paste (price/performance) that has better results with cleaning

More background please: * What is the condition of failure [eg, part damaged, part poorly attached, etc] * You mention heel and side fillets. What about under the component? * Are the components properly attached? Or are they floating on a bed of fl

Get a demonstration, on most packages these systems can see down a row. You don't see solder flux residue with X-Ray. You don't see the intermettalic bond with x-ray. They are some what expensive but together with X-ray you have an excellent quality

We need to clean the RMA flux residue on the PCBAs. The PCBA material is ALuminum base(Gold finish)stacked with Rogers Material PCB.Any solvent recommnedtaions? Is HCFC 141b a good solvent (quality & Price). we need to use vapor degreaser and also do

HI, just my 0,00001 cents Which preheat system does your wave solder has? for instance ? - IR ? - Bottom only ? - IR + Forced Air ? (bottom) - IR + Forced Air (bottom) IR top ? PCB thickness ? Appropriate preheat is important when looking to f

Hi smtspecialist (man I gotta get me a name soon), NO! Your oven cannot contaminate your process. Unless you have flux residues dripping on your board, there is nothing to worry about. Now having your operators switch from leaded to lead-free smo

We have a customer enquiry that requires PCB assemblies to be cleaned to J-STD-001 / -004 class 3. We use both water based and no clean process chemistries. No clean flux residues are not permitted and would therefore have to be cleaned. My question

Not really. A new Electrovert AquaStorm 100, in-line machine, is under $60K, for straight aqueous applications. The batch type from Aqueous Tech are like $35K I believe. $120K would be for a high performance in-line machine, such as the AquaStorm 200

Depending on the system you can program in a loop where if the board fails a contact to cycle the vacuum once or twice. it wears on the pins a little faster since you cycle 2 times (maybe more) per board but it could help increase the FPY. I know Gen
