ran an internet search on "intrusive reflow", out popped various links on the subject. Bob Willis was rather prominent on the topic's links. anyway seems intrusive reflow soldering specs are the same as conventional manual insertion (radial, axial)

Major advance: Productionization of SMT. Minor advances: * Realization and control of solder paste characteristics * Vision alignment controls in printers. * Evolution from mechanical centering [through laser alignment controls] to vision alignment

150*C/min * Determining the distance it takes to lower the delta temperature at the current conveyor speed: [150*C/min]/[25 inch/min] = 6*C/inch * Calculating how much of this 6*C/inch would be spread along the length of the 0805 capacitor: [6*C/inch

Hello I am having a problem with the flux in the wave solder, I am using a sonoflux 9000 this machine uses a air knife to spray the flux, it creates a mist that when hits the air knife pulls the mist up to the pallet where the board is, but for som

Tom, If you need the parts... I can quote and supply them.. A good tradesman can change these parts. You do not necessarily need a Yamaha trained guy to do it. The only issue issue after the exchange of the parts is calibration of the machine, which

Dear Industry experts, We have just developed a leadless, fluxless solder that can join various metals ) Al, Cu, brass, Steel, stainless and Titanium) and Ceramics ( Ruby, Quartz, Sapphires, glass, TiO2, etc) We intend to explore electronics and

We don’t do it often, but on a test failure, when the cost of a BGA relative to our confidence that we might have a questionable joint is high, we will flux it with a low solids no-clean flux and reflow it again. We don’t do it often enough, and d

Update: We have bought more reels to cover both lines and it has helped enormously. There were about 100 part numbers that were used on both lines over 300 times per year. The majority of them were less than $20.00 a reel. We have also been using My

Thanks for the comment regarding the CPH. In fact, the benchtop oven we have takes 7 minutes to complete a batch soldering, so you can imagine that our production volume will not be very high. We can parallelize PCB assembly and oven phase. But defi

We're attempting to seriously address this problem now. For us it is not the cost of the lost components as much as the loss of SMT efficiency holding a job waiting for a $5.00 reel of components and the cost of $20.00 to overnight ship. Our IT gro
