Hi, We have a customer who give us a 20K board contract each year. It's only thru-hole components.The baord is HASL plated. So we pass it into our wave. No problems. Recently, our customer decided to go into GOLD PLATED finish. We take the same re

Dave , you know it's your cheery disposoition I love.... Ok so the process: Process is Double sided reflow for SMT & PTH via the wave. Like I said or did I, I forget and can't check back...it's a spray fluxer with noclean mutlicore NR3s-06 water b

We are using NR300F from Alpha. Topside board temp is 220 deg. F. We have 3 bottom side convection preheaters, and we use a foaming fluxer. The machine (except for the rotary chip wave) is almost identical to the old econopak. An electrovert appl

180deg More important are the preheat and soakzones and temp ramps. How to check: I used to do it as follows: use a TEST-PCB with fixed thermocouples and connect it to the mole. Print the profile on transparant paper. do it again e.g. each week and

Hi, Can anyone help explain the benefits/disadvantages of bareboard pcb baking, as part of the pre-heat conditioning, before the bareboard pcb use in SMT production run? The pcb board is 200mm x 240mm panelized pcb board, and has 28 smaller pcb boa

I am not answering for Techguy2000, but I am chiming in here, I have the same problem. Our resistor packs are ceramic body with no leads, they have a metalized area reminicent of the old castelation leads of year gone by. The lead pitch is 50 mil

| Anyone having any conveyor rail shaking on Electrovert wavesolder machine model "Electra"? The conveyor shakes more with a pallet passing through the machine, particularly when the 20" pallet is passing from spray fluxer to the first pre-heater. He

Yes, doing the DoEs on your wave to achieve optimum settings that deliver the best results on your worst board is correct method. If not clear on the process, there are still wave solder process classes out there you can attend or hire in-house. If y
