Mini Soldering Defects Solder Pallet CE ISO 350 Maximum Temperature
Chuangwei’s standard PCB hold down is our low profile. It is unbreakable, ESD safe and guaranteed for the life of the pallet. The non-marring design applies 12 pounds of downward pressure without having to lift. Just twist! We also offer a high profile hold down, cam-lock and custom hold downs for connectors.
Chuangwei does not ‘tap’ the composite, we use all “metal to metal” fasteners ensuring a reliable and long lasting fixture.
We offer two sizes of extruded aluminum stiffeners and solder dams; for smaller pallets we have a 3/8” tall and for larger pallets we have a 3/4” tall design.
All pallets are engraved with the board name and our work order number for handy reference. All data associated with your pallet is stored to that work order number.
BOTTOM SIDE STANDARD FEATURES
All bottom side fasteners are made from 316 grade stainless steel. This eliminates solder sticking or wetting to the fastener.
All fasteners are thread locked.
Our goal is to design and build a solution that will give you:
1. Highest yields with the largest process window possible.
2. Easy to use tooling that will survive your manufacturing environment.
3. Fastest delivery times possible.
Process Suitability
The viability of this process route crucially relies upon being able to estimate the number and distribution of PTH components
which CAN'T be processed (with and without glue dotting) - These will have to be miniwaved or hand soldered.
which are likely to be poorly soldered - These will require further inspection and manual touch up.
This estimation may be done in three ways
If a PCB is available (preferably populated) - our sales engineers can rapidly evaluate your board.
If PCB design data is available we will process, analyse and remotely assess it.
You can do it using the rules presented below - our customers quickly find that the above two methods are easiest.

PTH Components Located Perpendicular to direction through wave.
A larger separation is required due to the solder having to flow "under"
component pockets.
Working your way around the underside of the PCB, identify which components
are parallel and perpendicular to the wave and assess the solderability of each
PTH connector by comparing the actual separation against the graph right.
Ideally you want to be above the line in all cases.
PCB Design Implications - for Board Designers - or respin
We are often called upon by our customers to help with identifying design respin opportunities.
We will identify problem areas within a board and suggest appropriate movements of components. (Ideally before the PCB is fabricated)
However for board designers reading this, can you remember another four "rules" (to compete with the hundred other rules you have to have floating
around in your head).
Keep large (height) SMT components away from PTH areas.
Leave the leading and trailing areas around PTH components as clear as possible.
DON'T put any SMT components within 3mm (0.12") of any PTH components.
DON'T put all PTH components in line along one edge of a board - leave some space to allow us to support the masking in the centre of the board.

FAQ
(1) Discount price yes&no ?
It is depending on the volume. The larger the volume is, the more discount you can
enjoy.
(2) Why your price is a bit higher than other Chinese suppliers?
To meet the requirement of different customers and areas, our factory manufactures
various kinds of quality for each item at a wide range of price. We can offer the
products of different quality levels depending on customer’s target price and quality
requirement.
(3) If I can get a sample ?
For existing samples (sizes not larger than 300*300mm) can be sent free of charge
but you just need to bear shipping charge, or you can provide your DHL, FEDEX,
EMS, UPS courier account number to us.
For bigger sizes, or customized samples, it depends on negotiation.
(4) If you can guarantee the quality of mass production is same
as the sample sent to me before?
Quality is our culture, is our life. We believe our products will give you a surprise.
Our warehouse staff will leave another same sample in our workhouse, and marked
your company name on it, which our production will be based on.
(5) How can you deal with quality issues after receiving the goods?
1) First you take photos of unqualified goods and then our sales staff will send
them to Manufacturing Department to verify.
2) If the problem is confirmed, our sales will explain the root cause and take
corrective actions in coming orders.
3) Finally, we will negotiate with you to make some compensation.
