Hi, No we did not look at Pillerhouse, We were not particular fond of "moving the product" principle to selective (i.e using a gripper over a static nozzle), as often this requires pallets, and our sister plant had already completed testing which a

�a va Frank? Well, popularity depends on the beholder. Never heard of your "Specnor" machine. US and Eurolanders take different approaches to conveying boards. * US: Finger conveyors * Eurolanders: Pallet conveyors Suppliers of wave solder machin

Does anyone know if there is any kind of industry standard for x-out pcb's coming from board houses. I have been seeing more and more pallets/panels coming from various board houses with alot of bad pcbs. I have been in the industry for a little over

A bunch of thanks guys, we will take this in consideration. BTW, we will not go for the v-grove in the panel (2x8 boards + the extra cut of areas). The board house recommended us to go for braces/hinges, since this thin pcb-panel could easily break w

This is an issue that we are seeing a lot! It used to be that the primary-side (component-side...top-side) had most of the active components. It was simple: reflow bottom first. Now, we are seeing both sides of the assembly having the same amount of

Which fixture material is LEAST LIKELY to warp? Please advise. We used ta have a Wave Optimizer but the corpulent engineer before me broke it before he left the company. Anywho, my next project is to design a wave fixture pallet which will work

Hi Jim Good Day yes we are using a pallet bottom support as well as top cover. The top cover are design such a way that the solder paste area is open. the type of solder is lead free type(Avantec-ecorel free) in one panel consists of 28 parts and e

Are you using wave solder pallets? I use same flux and solder as you do. I've seen this problem when some walls in the wave fixture cause a "shadowing effect"...if you enlarge those openings you will increase the dwell time eliminatting voids (if the

Another thing to look out for... Flex circuits, if not fixtured properly tend to move around and, well, "flex" during screen printing. At another place I worked, we fixtured the flex circuit on a SMT pallet on the corner tooling pins to "stretch"

Hi A, Your subject is black solder, but you decrribe the solder as dull? Dull solder joints could be dross related, or even flux related. Are there any other related defects? But "dull metal sufaces" makes me thing this board was subjected to so
