Solder Ball Harmonized Code

Cheap Solder Spheres (Who’s got balls?)

Every so often, when flip­ping through the Trade Jour­nals, there is an ad or a col­umn that will catch our eye. In the last few issues of the Semi­con­duc­tor Trade Jour­nals, Easy­Spheres has been run­ning this Ad, “Got Balls”. Every­time I see it, I can’t help but think, “Yep, you’ve got balls, alright… charg­ing so much for sol­der spheres!“These cer­tain­ly are not cheap sol­der spheres.

I don’t want to bash Easy­Spheres busi­ness mod­el, which is essen­tial­ly a dis­trib­u­tor of Kester Sol­der Spheres in small­er pack­ag­ing, as dis­trib­u­tors play an impor­tant role in the dis­tri­b­u­tion of goods to small­er cus­tomers, and I’m sure Easy­Spheres pro­vides good ser­vice to its cus­tomers. What I do want to com­ment on though, are the tiny pack­ages these end of being.

How to get cheap solder balls

When you deal with tiny sol­der spheres, 10,000 pieces can be small­er than a tea­spoon of spheres. Even going as high as a mil­lion might fill a table­spoon. The vol­ume of these spheres is real­ly tiny, and what most pur­chasers don’t real­ize is that the weight of the deliv­ery pack­ag­ing can eas­i­ly be 10x the weight of the goods sold. I under­stand that com­pa­nies all want to run on “Just In Time” inven­to­ry, but when you order such small order quan­ti­ties, take a sec­ond to think of the man­u­fac­tur­ing process of these spheres.

Any process that needs to run pro­duc­tion to churn out a tea­spoon of prod­uct is going to be expen­sive rel­a­tive to the quan­ti­ty pur­chased. We looked at this mod­el over and over again, and it just nev­er made sense to us. Yes, you can charge high prices for tiny pack­age quan­ti­ties, but our view is that the bet­ter deal for the cus­tomer is to sell 100x (yes, one HUNDRED TIMES) the amount of spheres — 1 mil­lion or (1 kkpcs) — for the same price as 3–4x (three to four times) that tiny amount.

What makes solder balls cheap?

To start the pro­duc­tion process to churn out essen­tial­ly small pieces of alloyed met­al is an expen­sive process for tiny amounts, but if pur­chasers can buy more of the mate­r­i­al, the price drops dras­ti­cal­ly. So no, we don’t typ­i­cal­ly sell less than one mil­lion pieces, but our prices on one mil­lion sol­der spheres is gen­er­al­ly less than the same price Easy­Spheres charges for 40,000 spheres.
