Hello !! I have a problem with my wave solder oven, in one of the products we made has connectors on one side of the pcb and in the other one has SMT components the process is kinda tricky on the SMT components we use an adhesive and put to the refl

We have a printer with Hawkeye 1700. The PCB side sometimes returns a distorted picture. It happens erratically, can be at startup or after a while, sometimes the machine works full day without problems. The only way to restore operation is disconnec

What's this 'metalic coating on both sides'? Is that like a 'two-sided board'? I expect that your 200�F is the primary side temperature just prior to entering the wave. If not, you need more juice [depending on your flux and all that]. [Some mode

Hi, We have spent the day trying to profile our Vitroncis Soltec Delta C wave with the new SN100C solder, but having problems with the heavy pins on some BNC connectors we are using. We have Interflux no residue flux, and we are using palettes, whi

Hi Sam, I have a feeling that what you're trying to communicate is that your DPAK's are skewing off the pad during reflow. This is caused by a thermal "mismatch" where the solder paste on one side of the DPAK becomes molten before the other, then th

| Read an earlier thread about using glass slugs to determine placement CPk. Can it actually be done this way? What's the procedure? Be interesting to know 'cause if it's feasible, I'd probably get myself a kit. None of us here are stat's experts

| On various PCB's after building processes,such as reflow, flowsolder and wash. The soldermask on the PCB's have become discoloured, like a 'marble' effect all along the solder side of the board, it is lighter in contrast than normal, although when

| I have a product using high temperature solder to connect terminal pins to a PCB. The board is single sided copper, no plaiting. The solder is 95% tin 5 % silver. The flux is low activity rosin. The product is a subassembly. When the product i

I have a recent design (1 component side only) that calls for 2 surface mounted antenna's (brass plated) to be mounted on a PCB. The problem arises when the PCB is 18x11.25 and has 15 to 20 PCB's in the pallet (IE weight, fixturing to hold the anten
