First of all, shouldn't allow SMT operators to edit/create recipes, only grant access to the well-trained only. You will put yourself at risk if you don't have good process rule of oven recipes. Newer oven models should come with software that has m

The reason I asked about using X-Y data (originated from the pcb files) is that if you bombsite the locations with the camera and program or adjust them individually, you run the risk of having to do it over and over when fiducials change, your fixtu

Besides, regulated power supply should be installed separately on the printing boards. When power and circuits share the same printing boards, it should be avoided that regulated power supply and circuit components are mixed or power and circuits sha

Thanks. It starts to make sense. There is a formula at the bottom of this page: http://www.circuitinsight.com/programs/50456.html It says: Stencil Thickness = 2.64mil + 0.0831 * pitch of component in mil. for 1.13mm, that gives exactly 0.16mm. So,

Phil, I had over 2k stencils VG and 5-6 frames and about 150changeovers per week. Frames get beaten up with time, hoses inside blow, aluminum tensioners change tension, start having nicks, springs inside wear as well. At some point you have to deal m

There is a big difference between SMD and SMT. One term denotes a device and the other a process.SMD, or surface mount devices, are electronic resistors that sit on a printed circuit board (PCB).SMT, or surface mount technology, is a method of placin

When a product is only assembled and visual inspected (no testing required), who becomes liable/pays for defective product, when the issue is not visual? If a customer is not requiring testing at the CM, technically they're only paying for a fully

Hello All, I recently had a case of excessive tin coming from a solder pot sample. The solder is SN63 but the results of testing had a 64.97% for Sn. The J-STD-001 spec is 61.5% to 64.5%. The pot is used to pre-tin wires which will then be solder

In general, it is safer to use a single alloy with a known composition and performance characteristics. If you need to change the alloy used in your selective soldering machine bath, it is advisable to consult with the manufacturer or a soldering exp

The equipment of Specialty Coating Systems and PVA is both simple to operate and maintain. Since it's a spray booth, constant maintenance is required or you risk having a serious headache. Our conformal coating line includes a double-sided UV oven, a
