Bob, I agree that these are all board shop issues. I think the only one that is related to the Hasl process is the surface mount solerability issues. I think they are still putting the coating on too thin even though they say it is fine. This proble

Cuculi, I'll have to go ahead and disagree with you. Very few PCB Suppliers (if any, and if there are any, they're lying) will promise an exact thickness spec. be it Sn/Pb HASL or this fancy, schmancy Sn100c HASL balogna. After all, the HASL proce

Now seen the Blow Holes and shallow inverted and non wetting problem an aweful lot over here. Over came the Blow Holes and shallow inverted joints by washing the bare PCB with hot Saponifier then rinse and dry = problem dissapears. Think most PCB ven

Good afternoon all! Theoretically, there should not be any issues soldering to the SN100C as the tin content of the molten paste alloy should wet to the finish with no problem. I would just ensure that the peak temperature of the joint is above the

Roland It's nice that Peter is considering improving the site. Things we'd like to see improved on SMTnet.com are: * SEARCH that works effectively. [We can't find postings that we've made. AND we know the key words. So, it must be painful for oth

Hi Basem, We are seeing a lot of our customers buying M2's & M4E's, and they are very happy with them. These are intellegent, profitable & well informed CEMs in the main, and for the money there is nothing else new that competes. Depending on wh

Hi Basem, The people I know are placing BGAs & down to 0201 with no problems. However the best thing for you to do is get them to demostrate placing your component range, and if you go ahead, draw up a machine acceptance document to form part of th

Thanks Rob. Our concern is placing tiny components side by side at a minimum pitch, along with fairly large BGAs and TSOP2, which are themselves, having small to fine pitch leads. yes, accuracy in placement in our application is crucial, yet, what i

Hi Basem, Juki have been around a long time - at least 15 years (formally branded Zevatech in Europe) & have a very large instal base. Their machines are good quality, but a little pricey. I have seen a number of them working with no problems in T

We've got a problem with our AP25.. I just finished repairing and calibrating this printer. We needed to replace the camera. After the cal. was done, the print accuracy was superb. However, it seems now, the consistency will not maintain itself. T
