There are too many(And in this forum we try not to paste the URL as much as possible to avoid the suspicion of advertising), you can search "邦定胶", then click "销量" to sort by sales, then you can see a lot of black bonding glue for COB. But the problem is that their heat limit is only 230 to 250 degrees, and the glass transition temperature is only 200 or lower, which is not enough. Lead-free reflow has a peak temperature of 260 degrees. it is unacceptable to ask my customers to use low melting point solder paste for my module. |
