Yes, you need work with supplier to see if can run pin in paste for these connectors, even do some experiments. A step-up stencil would be good for these connectors, also connectors pin size and length match with PCB hole design.

We have a potential new customer who has special PCB requirements. I do not know a lot of details at this point, but have several questions. One of their assemblies has within it , a MID, Solid foil layer, completely isolating one side of the PCB f

CRITICAL DILEMA! Has anyone run into the problem described below and if so, what was the fix (besides not dealing with this Supplier)? Also, we do not have component manufacturing process experience. We are purchasing a surge resistor that function

Our SMT production and storage area is air-conditioned, constant temperature is maintained but the humidity is not controlled , the raw SMT material is stored in a "Drier" cabinet, but since we assemble hybrid SMT and thru-hole PCB assemblies, the SM

wow, never heard of such a thing! Are you sure it's allways different types of material? Are you using a washer that isnt cleaned regular? I would check your product step by step, from bare PCB to finished product to find out where exactly in your

Hi Greg, You sound like a buyer or procurement professional. Everything you listed is OK, and more or less. Quite often Engineering Design or Product Management in the OEM establishes what they feel are some of the basic T&Cs. I guess I would ask

We sometimes use a peelable mask the the PCB manufacturer (board house) adds as part of their process. It may seem an expensive option but avoids: Raising P/o's for tape/peelable mask as consumables booking & inspection Booking out to the shop floo

Do you bond with Al or gold wire? What happens if the Ni is over 150 microinches? Thickness of nickel is one those things that we have not been consistent with. The industry seems to pretty much universally call for 100-200 microinches. Our old board

Simple differences. Both processes require a very similar machine platform, controlled motion, vision fiducial recognition and alignment of a substrate (PCB or hybrid ceramic) to the "image", the image being either a stencil (hence stencil printing)

Is the peelable mask (put on by the boardhouse) flat on the surface of the pcb? If so can you tell me the material name, so maybe I can find a picture? We have to print adhesive on the board, so the mask has to be flat. That is why Kapton from the b
