Checksum will work if all your doing is analog/passive testing. Checksum systems do not have digital test capability. I would recommend a Teradyne z18xx system. We use 8 of them in our plant and have been for years. Used, these systems range from

Sounds like a plan. The usual way is to count how many you use on the job either by pre-calculation. Or how many clicks the machine counts and save the data before switch off, then drop it back into a spread sheet. This depends very much on the mach

A common bottomside heater configuration is IR-Convection-Convection. One of the big advantages of the IR zone is its ability to allow the flux carrier to spread and dry slowly before the board reaches the convections zones, which can blow wet flux c

Hey Bill, it really depends on the material you're looking at using UR, SR, AR, the easiest to deal with being AR, although if you can find a UR that doesn't clog up the machine too bad those are usually more viscous and easier to apply selectively u

The backflow in the wave started to become very important with the development of no-clean/no residue fluxes. These fluxes don’t have (or at least shouldn’t have) rosin, resin or other vehicles in the formulation which encapsulate surface oxides from

In my limited experience. A Domestic Dishwasher with no water recycling like which is offered on some of the newer high priced models works a treat. Clearly this is batch. Inline filtering of the water supply is a good ideal. There are several ways o

Placing and re-flowing the shield is of course the most economical. But once the shield is placed and reflowed this all but rules out inspection test and rework. Reflow should not be an issue if you have a decent forced air convection oven. You may w

Well, the error occurs with Mod Code 56 (dispenser enable). Head # 1 has installed this accessory, but we use it very little and it wasn't this time. I probed setting 0,1,2 and 3. I downloaded Mod Codes from controller to assembler, then the error b
