Shawn: You're correct most solder preform manufactures don't want to sell preforms without skinning you alive for tooling charges!!! Considering alternatives, can you print or dispense paste? It would be mucho cheaper. We've talked about using pa

Hi Christopher, To my knowledge, heat seal along will not provide you the desire condition. Currently, we're using vacuum sealer to reseal all MSD restock items. If you have variety of package and constantly need to reseal the MSD parts, I'd like to

Dennis: Direct metalization is more of an European phenomena than a US one. Not to say that good things don�t come out of Europe. As background: Direct Metallization. In circuit board fabrication, an alternative to electroless plating makes the

Typically, Sn/Pb solders are used to preserve solderability on leaded and leadless SMT components. Are other finishes (such as those used in PCB manufacturing e.g. Sn, NiAu, OSP's, etc.) frowned upon by PCB stuffers and their customers? I am intere

John, I have read some of the follow-up's to your question and I am having several dry-cabinets made. Each, for under $500.00. Mcdry, a subsidiary of Seika Corp. is a vendor that has a solid background with moisture-free storage units. If cost is an

What time? An in-line bot with a vision system tuned for paste recognition can measure a different portion of each board and keep pace with the placement machine all day long. I don't understand what you guys propose as an alternative. Realistical

Yes, it makes sense that company peculiar issues should not be included in a general training program, but say the issue delt with: * Course indicating [through correct responses to testing] that component leads should not be handled because it could

You might want to check with Atlas Copco re the characteristics of the tool case. Although it is plastic, it could have been formulated to be dissipative. Unfortunately, with power tools there is always the conflict between the need to isolate the

For reflowed solder joints, Bi bearing solder has been reported to exhibit superior fatigue resistance. It also provides better wetting than many other alternatives, including SnAgCu systems. In my opinion, it may be the choice once all Pb can be pha

The conversion into Pb-free very likely will be dictated by the feasibility of conversion. Exemption may be allowed for those sectors facing greater challenges. For instance, the industry is having difficulty in finding acceptable Pb-free alternative
