Don't really know if fixing the damage would even fix the board. The cut is deep, short, and narrow, like it was stabbed with an Exacto point. There is visible disruption to copper in the second layer but we can't tell if there is an open, a short, o

Howdy, I have a Mirtec MV-TH2L bench top model and I like it. You could look at Yestech. They are in that range. The reason I like my Mirtec is that it programs up easily and does what we want it to do. So far in the last 4 months that we have ha

Hi John, They may still read the correct value initially, but they are not going to age well if the electrodes start oxidising. Also the high voltage surge performance & the impedance are likely to be effected, however these may be unimportant to y

Guys, My problem is that I have a 10 up panel and I have to use a selective pallet to run it thru the wave process due to SMT on bottomside. However the yields are very poor. We have done everything to improve them with some good improvements along

Good afternoon, 1. Yes, most of all I suspect the components. Could you explain what does mean "reflothermal recipe"? Ramp-to-spike? Ramp-soak-spike? Something special? Thanks. 2. Void is really huge. This voiding differs from "standard" voiding ef

A flying probe tester is a mid-speed placement machine with no feeders and the placement heads replaced with manufacturing defects analyzer test probe activator head. It is useful for testing bare boards, first piece inspections, and low volume prod

I think you have your pitch wrong but anyway, I have never had success with wave soldering anything less than 50 mil pitch. On a QFP I have had good luck on three sides of 25 mil but never all four sides and without defects. Mask 'em off and hand s

Hi, Has anyone got first hand experience with the JT wave soldering machines, WS series? I use a low solid VOC free flux and it seems I have problems atomizing the flux properly and this generates soldering defects, leaving lumps and big solder bal

I had a customer like this too. Originally, the customer print called for manual soldering of the RF shield (which took us about 20 min. per shield to hand solder), but I changed it to Solder Reflow (I cut apertures on the stencil), with brass weigh
