your comments will be appreciated, please; IC tests have been performed on two kind of Raw PCBs (HASL) samples by adopting three different methods : First Sample (supllier A) - Omegameter 600 SMT, solvent=40�C: extratcing time 10 min result = 0.2

Are you aware of Austin American Technology's "Mega" process. It combines MegaSolv chemistry with the Mega II cleaning system. MegaSolv is a single non-aqueous solvent which is deionized by the Mega thru a special solvent compatible mixed bed on-bo

Good morning, Our automatic cleaner simply doesn�t clean. When I am inspecting clogged apertures I execute �cycle wiper� command few times. After wiping cycle apertures remain clogged. Zero effect. We tried to use solvent in production to improve cl

Do you clean the stencil manually or using the automated under-stencil cleaner on your Printer (recommended)? 1. Ensure that stencil wipes are lint-free and soaked sufficiently with solvent before use. 2. If your printer supports automated cleaning

vapor degreaseing has two main flavors mono solvent and co-solvent. the later being the best performance Yes can clean PCB and in many ways is best in cycle time and cleaning quality. Is batch machine based usually or automated batch if budgets all

Using a vapor degreaser with a solvent such as Vertrel, Novec, Techspray 1655, Solstice, etc. may work for you but solvents can attack certain plastics. Should be fine for SMT though. This is assuming you are using a no-clean (RMA) type flux, not wat

I may be mistaken but I believe that the solvents have defoaming agents in them. I get less foam when I use the solvent than when I don't. If you dissolve the flux in water and agitate it I believe it will foam. I haven't had any over flow issues w

We are currently cleaning solder paste (TAMURA SQ-1030FP) from stencil using an ultrasonic stencil cleaner with solvent (HYSPER-Non CFC). The process cycle time is 30 sec. cleaning in 1st ultrasonic tank and another 30sec. cleaning in 2nd ultrasonic

From your stencil, if not clean, you can have residues, try increasing the frequency or using solvent with the wipe.
